Given :-

  • The perimeter of a rectangle is 42 inches.
  • The width of the rectangle is 6 inches.

To Find :-

  • The length

Solution :-

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.

Therefore, the correct answer is option (B) 15 inches.
