Theo made sails for a model boat. he cut along the diagonal of a rectangular piece of cloth to make two sails as shown below. what s the area in square feet of one sail?

Given:

A rectangular piece of cloth (dimensions):

L = length of the rectangle
W = width of the rectangle

The area of the rectangle is:

A = L x W

If the cloth is cut along the diagonal, the area of one sail will be half the area of the rectangle:

 A (one sail) = 1/2 (L x W)
