Question

Eric is building a parallelogram with a base that is 8 centimeters and an area of at least 56 cm? Which inequality represents all the possible heights of hisparallelogram?

Answer 1

The area of a parallelogram is its base multiplied by its height. Eric wants a parallelogram with area:

$\begin{gathered} A\ge56 \\ A=8\cdot h \end{gathered}$

So, the inequality is:

$\begin{gathered} 8\cdot h\ge56 \\ h\ge\frac{56}{8}=7 \\ h\ge7 \end{gathered}$
