Question

Suppose the length of each side of a

square is increased by 5 feet. If the
perimeter of the square is now 56 feet,
what were the original side lengths of the
square?

Answer 1

9 feet

Explanation:

(x+5)+(x+5)+(x+5)+(x+5)=56

4x+20=56

4x=36

x=9

CHECK

(9+5)+(9+5)+(9+5)+(9+5)=56

14+14+14+14=56

56=56
