The area of this quadrilateral is 52 square feet.
First, I noticed that the rectangle had sides which were 10 feet long and 4 feet tall. (10 × 4)
Second, I noticed that the triangles were 3 feet long and 4 feet tall. (3 × 4) Since this was a triangle, I then divided by 2. (3 × 4) ÷ 2 I then saw there were 2 triangles so I multiplied it by 2. [(3 × 4) ÷ 2] × 2
Lastly, the equation I was left with was (10 × 4) + {[(3 × 4) ÷ 2] × 2} = 5
