To determine how much of the wall is blue we first need to find its area. The wall is a rectangle, then its area is the product of its height and length:

Hence, the area of the wall is 140 square ft. To determine how much of the wall is already painted we multiply this by 1/2, then:

Therefore, 70 square ft are blue.
Known :
w = 12 feet
h = 18 feet
V = 3.240 feet³
Asked :
l = ...?
Answer :
V = l × w × h
3240 = l × 12 × 18
3240 = 216 l
l = 3240 ÷ 216
l = <u>1</u><u>5</u><u> </u><u>feet</u>
So, the length is 15 feet
