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.
288 inches
68 inches
18 inches
1/18 inch

Explanation:

Step1: Recall the formula for the area of a parallelogram

The formula for the area of a parallelogram is \(A = bh\), where \(A\) is the area, \(b\) is the base, and \(h\) is the height.

Step2: Solve for the base \(b\)

We know that \(A = 72\) square inches and \(h = 4\) inches. Rearranging the formula \(A=bh\) for \(b\), we get \(b=\frac{A}{h}\).
Substitute \(A = 72\) and \(h = 4\) into the formula: \(b=\frac{72}{4}\).

Step3: Calculate the value of \(b\)

\(\frac{72}{4}=18\).

Answer:

18 inches
