The perimeter of the square is 50 units\n\nThere are 5 rectangles that means the ratio of length to width has to be 5 to 1\nTherefore since each rectangle has a 5 to 1 ratio and a perimeter of 30 they are all 12.5 units by 2.5 units. (12.5 x 2 is 25, 2.5 x 2 is 5, 25 + 5 = 30)\nThe length of each side of the square is 12.5. 12.5 x 4 is 50 units

a: width\nb: length\nperimeter = 2 x (a+b)= 420 ---> a+b = 210\nwe need to find max (a x b)\n\na= 210-b ---> area = a x b = b x (210-b) = 210 - b2 = - b2 + 210b = - b2 + 2 x 105 x b - 105squared + 105squared\n= - (b2 - 2 x 105 x b + 105squared) + 105 squared\n= - (b - 105)squared + 11025\n\nSince (b - 105) squared is always >= 0,\n - (b - 105)squared is always <= 0\n  - (b - 105)squared + 11025 is always  <= 11025\n\nthe largest area will be 11025 squared feet. This happens when - (b - 105)squared = 0, which means b = 105.\n\na = 210 - b = 105\n\n\nthe shortest way is to say that a rectangle has the largest area when it's a square, so each side would be 420/4 = 105.

length x width = area\n3 x 6 = 18

a ) you effectively have a perimeter of 180m because 160 plus 20. \n\n so you take 180/4 because it;s retangle.  so your area would be 45 x 45 = 2025 m^2

Find the area.\nArea of a rectangle = length*width\n= 15*20\n= 300\n(2/3)(300) = 200\n300-200 = 100 square feet

2 * (l + w) = perimeter of rectangle\nl * w       = area of rectangle\nPerimeter of rectangle = Area in sqr units\n=> 2 * (l +w) = l * w\n=> 2*l + 2*w = l*w\n=> 18 + 2 * (x+1) = 9 * ( x +1 ) since l = 9 and w = x + 1\n=> 18 + 2x + 2 = 9x +9\n=>  11 = 7x\nHence x = 11/7

find the area of the cross section.... then times the area by the length... that is of course if it's a prism

It is \n[(35x1.50)+(15x1.75)+(20x2.25)]/70=\n123.75/70=\n1.77

I would go to Google and type in the search window 70.75 inches in centimeters\n\nIt tells the answer.  Then do the other 2.

Not enough information. If the rectangle is also a square, then the length of each side would be 32/4 = 8 cm. Letting x be the length of one of an arbitrary pair of sides and y represent the length of a side from the other pair, you do know of course that x and y must satisfy the equation 2x + 2y = 32 cm --> x + y = 16 cm. Since you have two unknowns but just one equation, there are uncountably infinite many possibilities for (x, y).

I'm not sure if this is what you're asking, but if...\nd = length\nd-3 = width\n\nthen the area is d(d-3), a.k.a. d^2 - 3d .\n\nHope this helps!

8X11\n\nThink about two boxes.  The outer box is 11X14.  The inner box is smaller, so you subtract.  You have to subtract 3 inches in each direction, so 11-3=8, and 14-3=11.

The dimensions of the rectangle are 5.5 cm x 16.5 cm\n\nIf the rectangle is 3x longer than it is wide, then there are four units that make up two sides...1 unit width, and 3 units length.  So we have four units (4x) that make up one half of the perimeter.  That means that eight units (8x) will make up the entire perimeter.\n\n8x = 44cm, therefore x = 5.5cm\nWe already said that one side is 3x and the other is 1x, so that gives us dimensions of 5.5cm x 16.5 cm

diameter is 70 means radius=35\nlenth=130\nso if it is the volume4 u want\n\nitssimply 2*3.14*35*130\n\nif not so question is in complete
