Answer: 83 inch²
Explanation:
First find the area of the rectangle:
= Length * Width
= 8 * 5
= 40 inch²
Then find the area of the first traingle:
= 1/2 * base * height
= 1/2 * ( 4 + 4) * 7
= 28 inch²
Then the second triangle:
= 1/2 * base * height
= 1/2 * (2.5 + 2.5) * 6
= 15 inch²
The area of the polygon is the sum of all these:
= 40 + 28 + 15
= 83 inch²
