Question

find the base of a parallelogram with an area (a) of 72 square inches and height (h) of 4 inches. use the formula for the area of a parallelogram, a = bh. 18 inches 68 inches 1/18 inch 288 inches

Explanation:

Step1: Recall area formula

The area formula for a parallelogram is $A = bh$, where $A$ is area, $b$ is base and $h$ is height.

Step2: Rearrange formula for base

We need to find $b$, so we can rewrite the formula as $b=\frac{A}{h}$.

Step3: Substitute values

Given $A = 72$ square - inches and $h = 4$ inches. Substitute these values into the formula: $b=\frac{72}{4}$.

Step4: Calculate base

$\frac{72}{4}=18$ inches.

Answer:

18 inches
