HELLO I REALLY NEED HELP WITH THIS QUESTION:
Felix calculated the area of a triangle with a base of 3 inches and a height of 1.5 inches. Edith calculated the area of a trapezoid with a height of 2 inches and parallel bases of 4 inches and 6 inches. Their work is shown below.
Felix's work:
A = 1/2bh
A = 3(1.5)
A = 45 inches2
Edith's work:
A = 1/2(b1 + b2)h
A = (4 + 6)2
A = 20 inches2
What error did they both make in their work?
They didn’t multiply by the base.
They didn’t multiply by the height.
They didn’t multiply by one half.
They didn’t use the right formula.
