What is area?
Area is a mathematical concept that expresses the size of a region on a plane or curved surface.

Given: A contractor is building a new subdivision.
A rectangular piece of land for a new house and yard is 60 feet wide.
The length of the land is longer than the width by a distance of n feet.
So, width = 60 feet
and length = 60 + n feet
Since, the area of rectangular piece of land (A)
Area = length x width
Area = (60 + n) x 60
Area = 3600 + 60n
Hence, the area of the land is 3600 + 60n.
