The area of the rectangle is:\n A of rectangle = L X W = 12 x 8 = 96 sq in\n\nThe area of the triangle is:\nA of triangle = 1/2 (A)(B) = 1/2 (A)(32 in) where A is the altitude to the base B of the triangle.\n\nsince both areas are equal:\n96 sq. in = 1/2(A)(32 in)\n96 sq. in = A (16 in)\nA = (96 sq. in)/16 in\nA = 6 inches

Area of a Rectangle\nA rectangle is a good, simple shape to begin with. The area of a rectangle is equal to the product of the length of its base and the length of its height. The height is a segment that is perpendicular to the base. For a rectangle, the base and height are often called the "length" and the "width", and sometimes the height is referred to as the "altitude." \n\nArea of a Parallelogram\nTo find the area of a parallelogram, we can use the same formula that we used for the area of a rectangle, multiplying the length of the base times the length of the height. \n\n\n\nLet's find the area of a parallelogram that has a base of 23 cm and a height of 7 cm. If we substitute the values into the formula, we find that the parallelogram has an area of 161 square centimeters\n\n&...

l = length\nw = width\n\nl = 8w\n\nlw = 128\n(8w)(w) = 128\n8w² = 128\nw² = 16\nw = 4\nl = 8(4)\nl = 32\n\nWidth is 4 feet.

The length of the wire must be (2x5)+(2x7)=24cm.  So each side of the triangle must be 24/3=8cm. long.

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

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.

Once again you will see that this is a rectangle.\nA = length times width\nA = 7*2\nA = 14

A = base * height\n\nbase = 8\n\nslant height = 6\nto get the actuall height, we use trig\n\nthink of 6 as the hypotenuse\n\nsin 30 = height / slant height\n\nor height = sin30 * 6\n\nheight = 3\n\ntherefore area = 8 * 3 = 24

(x+4)(2x+4)-2x^2=88\n2x^2+12x+16-2x^2=88\n12x+16=88\nadding -16\n12x=72\ndividing by 12\nx=6\nso the dimensions of the original rectangle are  6m*12m

The two "triangles" are not exact triangles, but rather are quadrilaterals.  The error in representation actually adds up to be one unit.  I have done the caculations in AutoCAD, and it turns out to be one square unit missing causing the extra space.

Rec first  8 X 4 = 32\n32 X 16 = 512  this is Area of rectangle.\n\nCircles pi X r^2 = Area\n3.14159 X 8 X 8 = 201\n\n512 - (2 X 201) = shaded area\n109.87 = shaded area\n\nOK ?

There are 12 inches in a foot.\n\nSo divide by 12.

The lenghth of the missing side is 20 in. because an isosceles triangle has only 2 alike sides so you multiply 26.5 X 2 and get 53in and then subtract 53in. from 73in. and get the 20in.

Sure, how about a triangle with a base of 3cm and a height of 4cm?\n\nA = 1/2 b * h\n6 = 1/2 b * h\n12 = b * h\n\nSo any numbers where b * h = 12 will work...\n1 cm x 12 cm\n2 cm x 6 cm\n3 cm x 4 cm\n0.5 cm x 24 cm\n1.2 cm x 10 cm\n2.4 cm x 5 cm\netc.\n\nAnd you can have a right triangle, or an acute triangle or an obtuse triangle... doesn't matter, as long as the base and height multiply to give 12...

If the perimeter is 36 and 1 side is 4, then you know by the rules of a rectangle that 2 of the sides are equal.  So if 2 sides are 4 each, that is a total of 8.  to find the length of the other two sides, you subtract 8 from the total perimeter 36 which gives you 28.  So the sum of the remaining two sides is 28 and by definition of a rectangle, they are equal.  So 28/2 is 14.  So 2 sides are 14 in length and 2 sides are 4 in length.  \n\nto find square footage, which is also the AREA of the rectangle, multiply LxW which is 14x4 which gives you 56.

well, you could be an architect and be using a 30-60-90 triangle and you needed to know a particular side of it. you can use x times the square root of 3, x being the shorter leg, to find the length of the longer leg.
