Calculating Area and Perimeter of Rectangles

The video tutorial explains how to determine the dimensions and area of a rectangular field given its perimeter. The field is three times as long as it is wide, and the perimeter is 1,200 feet. By setting up and solving the equation 2x + 6x = 1,200, the width is found to be 150 feet and the length 450 feet. The area is then calculated as 67,500 square feet.

What is the relationship between the length and width of the rectangular field?

• The length and width are equal.

• The width is three times the length.

• The length is three times the width.

• The length is twice the width.
