Question

The trapezoid below is made up of a square and a triangle. The total area of the trapezoid is 57.5 square meters. The area of the triangle is 32.5 square meters. What is the length of a side of the square?

Answer 1

5 m

Explanation:

The length of the side of a square is the root of the area of the square. The area of this square is the difference between the trapezoid area and the triangle area.

__

square area = trapezoid area - triangle area

square area = 57.5 m² -32.5 m² = 25 m²

Then the side length is ...

side length = √(square area) = √(25 m²)

side length = 5 m

The length of a side of the square is 5 m.
