Answer:
B: 340
Step-by-step explanation:
We are told that her walls are 8 ft high.
Now, Two walls are 10 feet wide. Thus, area of the first two walls will be;
A1 = 2 × (10 × 8) = 160 sq.ft
Also, the other 2 walls are 15 feet wide.
Thus, Area of other two walls will be;
A2 = 2 × (15 × 8) = 240 sq.ft
We are told that the combined area of the 1 window and the 1 door in her room in 60 square feet.
This means that we will subtract 60 Sq.ft from the sum of the area of the 2 walls earlier calculated to get the total area to be painted.
Thus;
Area to be painted = 160 + 240 - 60 = 340 Sq.ft
