Question

Mrs. Bryer is painting a mural on her rectangular classroom wall the wall is 10 feet long and 9 feet wide the mural will be 9 feet long and 8 feet wide how many square feet of the wall will not be covered by the mural

Answer 1

To find the area of the wall not covered by the mural, we subtract the area of the mural from the total area of the wall. The wall's area is 10 ft x 9 ft = 90 sq ft, and the mural's area is 9 ft x 8 ft = 72 sq ft. Therefore, the area not covered by the mural is 90 sq ft - 72 sq ft = 18 sq ft.
