Answer:the length of each side of the square is 11 feet
Explanation:
All the sides of a square are equal.
Let x represent the length of each side of the square.
If one side of a square is increased by 12 feet and the side connected to it is decreased by three feet, a rectangle is formed. It means that the dimensions of the rectangle formed are a + 12 and a - 3
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
The perimeter of the rectangle is 62 feet. Therefore
62 = 2[(a + 12) + (a - 3)]
62 = 2(2a + 9) = 4a + 18
4a = 62 - 18 = 44
a = 44/4 = 11 feet
