Question

The total area of two square windows is 1,025 in. 2. Each side of the larger window is 5 in. Longer than the sides of the smaller window. How long are the sides of the smaller window? a = s2 13. 5 in. 20 in. 25 in. 31. 6 in.

Answer 1

The sides of the smaller window is 20 inches long.

An equation that represents this situation is shown below, where s is the length of the smaller window
1,025 = (5 + s)^2 + s^2

if s = 20 m, then:
(5 + 20)^2 + 20^2
= 625 + 400
= 1,025
