If the length of each side of a square is decreased by 4 in

If the length of each side of a square is decreased by 4 in., the perimeter of the new square is 10 in. more than half the perimeter of the original square. What are the dimensions of the original square?

Solution

Solution: - let the length of the square = x

Perimeter of the square = 4x

Length of new square = (x -4)

Perimeter of new square = 4(x -4) = 4x -16

Given 4x -16 = 2x +10

2 x =26

x = 13\"
