Question

13. What is the area to be painted on two 16 ft by 30 ft

walls that each contain one 3 ft by 5 ft window and
a 3 ft by 7 ft door?

Answer 1

888 ft²

Explanation:

The total area of two wall is 960 ft² got when multiplied length by breadth (2x16x30=960)

But we need to exclude area for two windows (2x3x5 = 30 ft²) and two doors (2x3x7=42 ft²)

So 960 - 30 - 42 = 888 ft²
