Question

A rectangular window 5 feet by 2 feet is on a rectangular wall 9 feet by 18 feet. The rest of the wall needs to be painted. Approximately how many square feet of the wall needs to be painted?

Help, please :)

Answer 1

Explanation:

Step 1: Find the area of the window

`Area = l * w`

`Area = 5 * 2`

`Area = 10 ft^2`

Step 2: Find the area of the wall

`Area = l* w`

`Area = 9 * 18`

`Area = 162 ft^2`

Step 3: Find the difference

`Area \ of \ Wall - Area\ of\ Window`

`162 - 10`

`152 ft^2\ need \ to\ be\ painted`

Answer:
`152 \ square\ feet`
