Answer:
<h2><u>
72 square units</u></h2>
Step-by-step explanation:
First let's find the area of the middle rectangle.
We know the width of this rectangle is 6 and the length is 8 so we will multiply these two numbers.
6 × 8 = 48
Now let's find the area of the triangles
The formula is ((length × width) ÷ 2)
The width is 3, as it is not part of the rectangle, and the length is 8
And there are two triangles so we will do this twice
((8 × 3) ÷ 2) = 12
((8 × 3) ÷ 2) = 12
Now add up all of the areas
48 + 12 + 12 = 72
<u>So 72 is our final answer</u>
This is the commutative property
