Poster has a length of 10 ft and a width of 4 ft. New poster is redone and has a width of 2 ft. What is area of new poster?

The area of a rectangle is calculated by multiplying its length by its width.

For the original poster:
Area = length x width
Area = 10 ft x 4 ft
Area = 40 square feet

For the new poster:
Area = length x width
Length remains the same at 10 ft
Width is now 2 ft
Area = 10 ft x 2 ft
Area = 20 square feet

Therefore, the area of the new poster is 20 square feet.
