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
Edith's work:
A = 3bh
A = (b + b2)
A = 3(1.5)
A = (4 + 6)2
A = 4.5 inches
A = 20 inches?
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
