Answer:
I think the answer is 255cm squared
Explanation:
If you look at the shape it has 2 shapes. A rectangle and a triangle.
17-10 to get the height of the triangle = 7
22-12 to get the base of the triangle = 10
The area to find a triangle is 1/2 * b * h
= (7 *10) / 2
= 35
To find the rectangle =
22 * 10
= 220
To find the area of the whole thing =
35 (triangle) + 220 (rectangle) = 255cm squared
