Answer:
20 square feet^2
Explanation:
The computation is shown below:
As we know that
The area of a triangle is
= 1 ÷ 2 × base × height
Now for the one triangle is
= 2 × 4 ÷ 2
= 4
No multiplied it by four sides
So, it would be
= 4 × 4
= 16
And, the base of the sqaure is
= 2 × 2
= 4
So, the overall shape would be
= 16 + 4
= 20 square feet^2
