Question

the area of the parallelogram below is 280 m². what is its height? (not drawn to scale) 20 m a 28 m b 14 m c 7 m d 12 m

Explanation:

Step1: Recall area formula

The area formula of a parallelogram is $A = base\times height$, denoted as $A = b\times h$.

Step2: Substitute known values

We know $A = 280m^{2}$ and $b = 20m$. So, $280=20\times h$.

Step3: Solve for height

To find $h$, we use the formula $h=\frac{A}{b}$. Substituting the values, we get $h=\frac{280}{20}=14m$.

Answer:

B. 14 m
