Question

The shaded triangle has an area of 22 ft².

Find the area of the entire rectangle.
Be sure to include the correct unit in your answer.

Answer 1

Explanation:

A triangles area is half of a rectangle, so you would double 22. 22x2=44ft^2
This would be because the formula for the area of a triangle is the base times height all divided by 2. The area of the rectangle is base times hight, so a triangle’s area is half of that of a rectangle.
