Question

Find the height of the trapezoidA=80 CM2 7Cm9CM

Answer 1

The area formula for trapezoids is

`A=((B+b)h)/(2)`

Where B = 9 cm, b = 7 cm, and A = 80 cm2. Let's replace these dimensions to find h

`\begin{gathered} 80=((9+7)\cdot h)/(2) \\ 160=16h \\ h=(160)/(16) \\ h=10 \end{gathered}`

Hence, the height is 10 cm.
