The area of a rectangular dog pen is 8/1/2 square feet. if the width is 3/2/5 feet what is the length in feet

l = 2 1/2 ft

Step-by-step explanation:

The formula for A is l*w for a rectangular length

A= lw

Putting in what we know

8 1/2 = l * 3 2/5

I will change mixed numbers to improper fractions

8 1/2 = (2*8+1)/2 = 17/2

3 2/5 = (5*3+2)/5 = 17/5

17/2 = l*17/5

Multiply both sides by 5/17 to isolate l

5/17* 17/2 = l* 17/5 * 5/17

5/2 = l

Changing this back to a mixed number

2 1/2 = l
