Answer:
70 inches²
Explanation:
We can break this shape up into 5 different shapes.
Two triangles, and three rectangles.
The three rectangles will be A = L * W and are all the same size,
A = L * W
A = 3(L * W)
A = 3(10 * 2)
A = 3(20)
A = 30 inches²
Now, we need to find the area for the two triangles. Usually, you would take the base times the height and divide by two, but since we have two triangles of the same size we do not need to divide by two,
A = B * H
A = 10 * 4
A = 40 inches²
Last, we will add the two areas for the triangles and rectangles together,
40 inches² + 30 inches² = 70 inches²
