Question

Mrs. Jones wants to paint a wall but not the door on the wall.

How many square feet of wall does Mrs. Jones need to paint?

Answer 1

the answer is 129 square feet

Answer 2

129 square feet.

Explanation:

10x15= total area of the entire wall.

10x15=150

3x7=total area of the door

3x7=21

150-21=total area of just the wall and not the door.

150-21=129

answer: 129 square feet.

OR

15x3=45

7x6=42

7x6=42

45+42+42=129
