add 21 and 13 and double the answer!
Assuming it is rectangle, then the perimeter equal twice the summation of length and width. Answer = 2 x (14 + 24) = 2 x 38 = 76 inches
A rectangle with a perimeter of 36 units can have sides of any length as long as the lengths of the two differently-sized sides are equal to 18. For example, a rectangle with sides of 10 units and 8 units (don't forget to state what these units are, whether they are inches or centimetres or any other similar measurement), would have a perimeter of 36.
P = perimeter, L = length, W = width P = 2L + 2W = 2(8) + 2W = 2W + 16 = 46 2W = 30 W = 15 So as long as x is 15 inches or more, it will have a perimeter at least 46.
To find the length of each side of the square, we need to divide the perimeter by 4 since a square has four equal sides. Therefore, if the perimeter is 24 inches, each side would be 24 inches divided by 4, which equals 6 inches. So, each side of the square would be 6 inches long.
If the length is 15.5 feet then the combined length of the two long sides is 31 feet, this leaves 9 feet, which divided between the two shorter sides means each must be 4.5 feet long or 4 feet 6 inches long if you prefer.
Perimeter = 12+12+7+7 = 38 inches
That is not a square, it is a rectangle and it has a perimeter of 36 inches.
26 feet.
124 inches
find the perimeter and area of a rectangle that is 15cm long and 5cm wide
36 inches
Add the length and the width; Double the answer; Job done.
110
16 inches
It would be 15 inches long.
Perimeter: 7+3+7+3 = 20 inches Area: 7 times 3 = 21 square inches
If a rectangle is 40 inches. the rectangle is 12 inches long then: 2 * 12 + 2 * width = 40 2 * width = 40 - 2*12 = 40 - 24 = 16 width = 16 / 2 = 8 So the width of the rectangle is 8.
