The area of the lawn before the purchase is 37500 ft² while the area after the purchase will be (37500 - 250x)ft²
The formula for calculating the area of a rectangle is expressed as:
A = LW where
L is the length
W is the width
Given the dimension of a rectangular lawn to be:
Length = 150 feet
Width = 250 feet
Get the area of the rectangular lawn as shown
A = 150 * 250
A = 37500 ft²
For the rectangular strip of land
Its length = x feet
Width = 250foot
Area of the rectangular strip = 250x ft²
Hence the area of the lawn before the purchase is 37500 ft² while the area after the purchase will be (37500 - 250x)ft²
