Let the side of the first square be x.
The side of the second square is y.
Given that the side of square 1 is 5 cm shorter than square 2.
==> x = y-5 ...........(1)
Also, the area of the larger square ( square 2) is 4 times the area of square 1.
==> y^2 = 4*x^2 .........(2)
We will solve by substitution.
We will substitue (1) into (2).
