The perimeter of a rectangular building is 1200 feet. The width of the building is 2 feet less than three times the length. What is the width of the building?

Given:

The perimeter of a rectangular building is 1200 feet.

The width of the building is 2 feet less than three times the length.

To find:

Width of the building.

Solution:

Let length of the building be x.

Then, width = 3x-2

We know that,

Add 4 on both sides

Divide both sides by 8.

Now,

Therefore, the  width of the building is 449.5 feet.
