36 inches
That is not a square, it is a rectangle and it has a perimeter of 36 inches.
26 feet.
124 inches
Perimeter = 12+12+7+7 = 38 inches
110
It would be 15 inches long.
16 inches
Perimeter: 7+3+7+3 = 20 inches Area: 7 times 3 = 21 square inches
add 21 and 13 and double the answer!
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.
By Pythagoras, the other side is 24 inches long. So the perimeter is 2*(10+24) = 2*34 = 68 inches.
