The width of a rectangle is 2 cm less than its length. The perimeter is 52 cm. What is the length ?
Let its length be x cm.
It is width will be (x-2) cm since it is 2 cm less than the length
Perimeter of a rectangle is given by the formula 2(L+W).
So 2(x + (x-2)) = 52
2(2x -2) = 52
4x- 4 = 52
4x = 52 + 4
4x = 56
x = 56/4 = 14 cm
So its length is 14 cm and its width is (14-2) cm, which is 12 cm.
