A rectangular garden has an area of 37 square miles. If its length is 28 miles, what is its width?
Semmy [17]

Answer:

\frac{37}{28} miles

Step-by-step explanation:

Use the area formula, A = lw, where l is the length and w is the width.

Plug in the area and length into the formula, and solve for w:

A = lw

37 = 28w

37/28 = w

So, as a fraction, the width of the garden is \frac{37}{28} miles
