The perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches, what is the length? А. 12 inches
B. 15 inches
C. 21 inches
D.40 inches

We know that,

☆ Perimeter of a Rectangle = 2 (length + width)

Hence,

42 = 2 (length + 6)

or, 42/2 = length + 6

or, 21 = length + 6

or, length = 21 - 6

or, length = 15

The length is 15 inches.
