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 )
= W
