Problema Solution
Each side of a square is lengthened by 5 inches. The area of this new, larger square is 49 square inches. Find the length of a side of the original square
Answer provided by our tutors
let 'x' represent the original length of the square's sides
area = l^2, where 'l' is the length of a square's side
49 = (x+5)(x+5)
solving for 'x' we have x=2
the original square was 2 in on each side
