Answer: 88
Explanation:
First, separate into familiar shapes
The area of the triangles at each side is 10 because the formula is length times times width divided by 2, when you plug the numbers in, 5 times 4 divided by two, times 2 because there are two triangles which equals 20.
That leaves the rectangle and the formula for the area of a rectangle is length times width, 17 times 4 which equals 68.
Add them, 20 plus 68 equals 88.
