Answer:

see explanation

Explanation:

perimeter (P) is calculated as

P = 2L + 2W (L is the length and W the width )

given P = 48 and L = 16 , then

48 = (2 × 16) + 2W

48 = 32 + 2W ( subtract 32 from both sides )

16 = 2W ( divide both sides by 2 )

8 = W

that is the width is 8 inches

-------------------------------------------------------

P = 2L+ 2W ( subtract 2L from both sides )

P - 2L = 2W ( isolate W by dividing both sides by 2 )


(P-2L)/(2) = W
