Answer:
200 inches
Explanation:
Because we are finding the area of this triangle, we have to use this formula. A (area)= 1/2 × b (base) × h (height).
First, multiply 20 by 20.
20x20=400
Now, for the final step, because this shape is a triangle, we have to divide by 2.
400/2=
200
The area of this figure would be 200 inches.
Hope this helps!~
