Answer:

9 inches

Explanation:

The perimeter of a rectangle can be found using:

p=l+l+w+w , or

p=2l+2w

We know the width is 5, so we can substitute 5 in for w. We also know the perimeter is 28, so we can substitute 28 in for p.

28=2l+2(5)

Multiply

28=2l+10

Subtract 10 from both sides

18=2l

Divide by 2 on both sides

l=9

The length of the rectangle is 9 inches

Hope this helps! :)
