Question

A piece of cloth was cut in the shape of a trapezoid. The two bases measured 32 cm and 24 respectively with the height of 50 cm. What might be its area?A.212cm²B.818cm²C.1,400cm²D.2,800cm²

Answer 1

$C)1,400cm^2$

1) The area of a trapezoid can be calculated by using this formula:

$A=\frac{(B+b)h}{2}$

2) So now, let's plug into the formula the given data. Notice that B refers to the largest base as well as b to the smallest one.

$\begin{gathered} A=\frac{(32+24)50}{2} \\ A=\frac{(56)50}{2} \\ A=\frac{2800}{2} \\ A=1400\:cm^2 \end{gathered}$

Note that area measurements require squared units.
