A factory is to be built on a lot measuring 150 ft by 200 ft. A local building code specifies that a lawn of uniform width and equal in area to the factory must surround the factory.

Answer 1

Draw and label a diagram!

w represents the width of the lawn.

(200 + 2x)(150 + 2x) - (200)(150) = (200)(150)

The lawn is a "doughnut" and the factory is ht e"hole."

Area of doughnut must equal area of hole.
