A rectangle has a length of 10 inches and a perimeter of 48 inches. Which equation could be used to find the width of the rectangle?

A48 = 10w
B48 = 20 – 2w
C48 = 40w
D48 = 20+2w

Verified Answer :

D48=20+2w
because the perimeter (48) is equal to 2 times the width (2w) and 2 times the length (2*10)
