What is a rectangle?

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

A rectangular section of granite is being cut so that the length is 3 times the width.

The perimeter of the section must be less than 320 inches.

The perimeter of the rectangle will be given with inequality will be

P > 2(L + W)

We have

L = 3W

Then the inequality equation will be

320 > 2 (L + L/3)

320 > 2 (4L/3)

320 > 8L/3

    L < 120 inches

Then the length of the granite must be less than 120 inches.

Then the correct option is D.
