Question

ms. davis bought farmland for her cattle. the land is rectangular and has an area of 72,000 square feet. if its length is 900 feet, how wide is it? a 90 ft b 100 ft c 70 ft d 80 ft

Explanation:

Step1: Recall area formula

The area formula for a rectangle is $A = l\times w$, where $A$ is area, $l$ is length and $w$ is width.

Step2: Rearrange formula for width

We can rewrite the formula as $w=\frac{A}{l}$.

Step3: Substitute values

Given $A = 72000$ square - feet and $l = 900$ feet, then $w=\frac{72000}{900}$.

Step4: Calculate width

$\frac{72000}{900}=80$ feet.

Answer:

D. 80 ft
