Question

Bill wants to put a large mural on a wall that is 9 and 1/3 feet long and 8 and 1/8 feet wide. Find the area of the wall. If the mural is 100 square feet, will it fit on the wall

Answer 1

If you would like to know what is the area of the wall, you can calculate this using the following steps:

area = length * width
area = 9 1/3 feet * 8 1/8 feet = 28/3 feet * 65/8 feet = 455/6 = 75 5/6 square feet

The area of the wall is 75 5/6 square feet. 

If the mural is 100 square feet, it won't fit on the wall, because 100 > 75 5/6.

Answer 2

A=(length)(width)
A=(9 1/3)(8 1/8)=(28/3)(65/8)=1820/24=75.83
100>75.83 ft^2
Yes, the mural will fit on the wall.
