p = 75+75+45+45=240cm a = 75 x 45 = 3375cm

{x, y} = {3, 5}.

There no such thing as perimeter of 3D objects . Generally perimeter is for 2D objects but you can find the surface are of a cube if you wished to ask that. Surface area of cube is - 6 x side x side.

A pentagon is a 5-sided figure, and the perimeter is the sum of the lengths of all the sides. A pentagon with 15-inch sides, will have 5 x 15 inches = 75 inches as its perimeter.

how do you find the area of a rectangle witha perimeter of 36 in You don't. You need more information For example a 1 x 17 rectangle has a perimeter of 36 and its area is 17. But a 2 x 16 rectangle also has a perimeter of 36 and its area is 32.

The answer will depend on what x is.

A+ =7

You cannot solve this equation without knowing the shape.

.75/x=.33

(70 + 75) x 2

There's not enough information here to figure that out. If it was a square, we'd know it was 15 x 15 and the perimeter would be 60. But there are four possible whole number rectangles with differing perimeters. 250 x 1, perimeter 502 75 x 3, perimeter 156 45 x 5, perimeter 100 25 x 9, perimeter 68

what is the value of x so that the perimeter of the rectangle shown is at least 92 centimeters

p = 75+75+45+45=240cm a = 75 x 45 = 3375cm

27 is 75% of: Let x = value you are looking for 27 = 75/100 x 27 = 0.75 x 27/.75 = x 36 = x or x = 36 36 is the answer. Check: 36 * 75% = 27 so answer checks out.

If your shape is a rectangle then your y=30cm

Since the perimeter is already known and there are no additional values of sides, nor is the shape known, one would mathematically say the x = 24 cm.
