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 ).

( \frac{1}{18} ) inch

18 inches

68 inches

288 inches

Explanation:

Step1: Rearrange the formula for base

Given \(A = bh\), we can solve for \(b\) (base) by dividing both sides of the equation by \(h\). So \(b=\frac{A}{h}\).

Step2: Substitute the values of \(A\) and \(h\)

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

Step3: Calculate the value of \(b\)

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

Answer:

18 inches
