Question

A piece of wire x cm long is to be cut into two​ pieces, each bent to make a square. The length of a side of one square is 15 ​times the length of a side of the other. Express the sum of areas of the two squares in terms of x.
x = 4s + 4(15s) = 4s+60s = 64s
A = (4s)^2 + (60s)^2 = (4x/64)^2 + (60x/64)^2 = 113/128 x^2
