Simon says that to find the area of a trapezoid, you can multiply the height by the top base and the height by the bottom base.
melomori [17]

Answer:

Yes, Simon is correct.

Step-by-step explanation:

A trapezoid refers to a quadrilateral that is convex in shape; as such it has no equal sides and no parallel sides.

Let the height of a trapezoid be h.

Let the top base of a trapezoid be b1.

Let the bottom base of a trapezoid be b2.

Area \; of \; trapezoid = \frac {1}{2} * (Sum \; of \; nonparallel \; sides) * height

Therefore, Area \; of \; trapezoid = \frac {1}{2} * (b_{1} + b_{2}) * h

Area \; of \; trapezoid = \frac {1}{2} * (b_{1}h + b_{2}h)

Area \; of \; trapezoid = \frac {b_{1}h + b_{2}h}{2}

Hence, to find the area of a trapezoid, you will multiply the height by the top base and the height by the bottom base. Then you add the two products together and divide the sum by 2.
