Question

A composite figure is formed by combining a square and a triangle. Its total area is 35.5 ft2. The area of the triangle is 26.5 ft2. What is the length of each side of the square? Complete the explanation. The area of the square is ft2, so each side of the square is ft.

Answer 1

First you do 35.5ft2 – 26.5ft2 to find the area of the square.
You get 9ft2 as your answer.

Then you would find the square root of 9, which just happens to be 3.

Each side of the square = 3ft
