what is the perimeter of a triangle which sides measure 6,8,and 10 inches?

The perimeter is the distance around the edge so in this case you would add 6, 8 and 10 together to get 24 inches.

Drop a perpendicular to side of length 10 from the vertex where the side of length 8 ends.\n\nA right angle triangle is formed,\n\nthe perpendicular is 8*sin 60 = 4sqrt(3)\n\nArea of ||gm is 10*4*sqrt(3) = 69.282 approx.

Generally, midpoints divide the lengths into half. So then, the whole perimeter of LMN is 1/2 of ABC. So the ratio is 1/2.\n\nYou can pick two CORRESPONDING sides, and their ratio is still 1/2. To find the area, there's a formula:\n\n(Side 1/Side 2)^2\n\n(One length of LMN/One length of ABC)^2\n= (1/2)^2\n= (1^2)/(2^2)\n= (1)/(2*2)\n= 1/4\n\nNote: one length of LMN doesn't have to be 1 and another length of ABC doesn't have to be 2. They can share common multiples, but you end up simplifying to ratio 1/2.\n\nratio of perimeter of triangles LMN to ABC is 1/2\nratio of areas of triangles LMN to ABC is 1/4

You give two sides lengths, 10 , 15\nThe length of the other two sides are:\n15*(9/10)= 13.5 \n10 + 6.538348415 = 16.538348415

definitely 63 square inches. The formula to find the area of a triangle is A=(1/2) x base x height. That is 0.5 times base times height. So, if you plug in the numbers, you get\n0.5 x 14 x 9 square inches\n(0.5 x 14) x 9 square inches\n(7) x 9 square inches\n63 square inches\n\nMake sure that whenever you look for the area of the triangle, the problem tells you that the numbers are the height and base.\n\nYes, 24 is correct.

Can you complete the question ? \n\nFYI : Perfect triangles are triangles with sides of integer length and having numerically equal integer area and perimeter.\n\nEg. Triangle with sides of length 6,8, and 10 units.

We know that the width is 5 yards, and that the length is double that, we can deduce that the length is 5x2=10.  So the rectangle is 5x10.\n\nThis means that the perimeter is 5x2+10x2=30 yards.  Since there are two sides length wise, and two width wise.\n\nThe area is the length times the width, 5x10=50 square yards.\n\nAgain, if you want to grow as a person you need to solve these yourself.  The time it took you to copy all these questions onto Yahoo! you should have been able to answer them yourself.  If you don't know how, you should be asking your teacher to explain them and give you extra tuition.

16.72 inches squared.\n\n\nDivide an equilateral triangle into two equal right triangles (meaning, draw the height).  The right triangles will have angles of 30, 60, 90, right (an equilateral triangle has 3 60 degree angles)?\n\nThe ratio of the sides in such a right triangle (the smallest leg being a) is a:a(sq(3)):2a, where 2a is the hypotenuse and a(sq(3)) is the other leg.\n\nThe "other leg" in this case is the height.  So a, half of the length of the side of the whole equilateral triangle, is 5.382/sq(3).\n\nMultiply this by 2 to get the whole length of the side.  We have our base and height.\n\n\nThe area of an equilateral triangle is 1/2bh.  b=2(5.382)/sq(3)\nh=5.382\n\nPlug those in and you get 16.72.

3 feet is 36 inches.\n\n0.8 feet is 8/10 of a foot. Solve 8/10 = x/12 for x, and you get 9.6 inches.\n\nSo 3.8 feet is 36 + 9.6 inches, or 45.6 inches.

Here's the process you would use to solve the problem.\n\nFirst, you need to know that an isosceles triangle has two equal sides.\n\nTherefore, you have two variables in the problem\n                    x = length of leg (there are two of these)\n                    y = length of base\n\nWe know that "the length of one of the equal lengths of an isosceles triangle is 8 cm les than 4 times the length of the base."  Therefore, we can write "x" in terms of "y":\n\n                    x = 4y - 8\n\nFurthermore, we know that the perimeter is 29 cm.  Now we can set up an algebraic expression to solve for "x."\n\n2x + y = 29   (initial equation)\n2(4y-8) + y = 29 (substitution)\ny = 5 (solved)\n\nWe have the length of the base ("y").  Now we can solve for the length of one of the equal legs.  Remember from above that\n\nx = 4y - 8\nx = 4(5) - 8\nx = 12\n\nSolved!\n\nIf you are still confused, draw an isosceles triangle to visualize the problem.  Label the base "y" and the two legs "x."

Just add up the lengths of the three sides. Works for any triangle - wether it's equilateral, isosceles or obtuse.

A hexagon has 6 sides.

Okay, I got something really different, but it might be wrong, I used tangents and stuff to figure it out, and I assumed a dodecagon had 12 sides, but I might be wrong. Anyways, I got 38.4 for the perimeter, and 115.2 for the area.

Well, a rectangle is not a triangle it is a parallelogram, I think. It has four right angles and two long sided and two short sides. Therefore, the dimensions are as follows: To figure area it is short side * long side. To figure how long all sides are you simply do two short sides plus two long sides. However, I am assuming that this was trick question to see who is paying attention to what a rectangle is.

The perimeter of the triangle is 48 so you divide that by 4 and the length of each side is 12 inches
