Question

Ingrid needs to paint her bedroom walls. The room is 9ft tall by 12ft wide and 11ft long. It has a door that is 7ft tall by 3.5 ft wide and two windows 3.5 ft by 3.5ft that don’t need paint. How many gallons of paint should Ingrid buy if 1 gallon covers 102 square ft?
A. 2 gallons
B. 3 gallons
C. 4 gallons
D. 5 gallons
E. 6 gallons

Answer 1

The answer is C. 4 gallons

Answer 2

Answer: The answer is 4 gallons

Step-by-step explanation: 4 gallons = 2 x (14 + 10) x 8 = 384 sq ft

windows = 2 x 2 x 5 = 20 sq ft

door = 4 x 7 = 28 sq ft

total = 384 - 20 - 28 = 336 sq ft.

336/350  is rounded up to 1 gallon
