Question

First try was incorrect 2 The area of the trapezoid below is 20 mm . Find the height. Round to the nearest tenth if the answer is in decimal form. 6 mm h 5 mm 4 mm

Answer 1

$\begin{gathered} \text{Area =}\frac{(4+6)}{2}\cdot h \\ \text{Area =20mm}^2 \\ 20=\frac{(4+6)}{2}\cdot h \\ 20=5\cdot h \\ h=\frac{20}{5} \\ h=4\operatorname{mm} \\ \text{the height is 4mm} \end{gathered}$
