Question

The perimeter of a rectangular sandbox is 34 feet if the length of the sandbox is 8 feet what is the width of the sandbox

Answer 1

The perimeter of a rectangular is:
P=2(l+w)
P=perimeter
l=length
w=width

P=2(l+w)
34=2(8+w)
34=16+w
w=18

Answer 2

L= length
W= width

Perimeter= 2L + 2W

substitute the known numbers
34 ft= 2(8 ft) + 2W

34= 16 + 2W
subtract 16 from both sides

18= 2W
divide both sides by 2

9 ft= W


ANSWER: The width is 9 feet.

Hope this helps! :)
