Question

You want to paint the walls of your bedroom. Two walls measure 12 ft by 7 ft, and the other two walls measure 13 ft by 7 ft. The paint you wish to purchase must be purchased in one-gallon cans and costs $17 per gallon. Each gallon will cover 400 ft2 of wall. Find the total amount you will spend on paint.

Answer 1

$17.00

Explanation:

Measurement of two walls of the room = 12 ft by 7 ft.

Area of the wall = Length × width

Area of two walls = 2(12 × 7)

= 168 feet²

Measurement of other two walls of the room = 13 ft by 7 ft.

Area of the wall = Length × width

Area of two walls = 2(13 × 7)

= 182 feet²

Total area of the bedroom to paint = 168 + 182 = 350 feet²

Each gallon will cover 400 ft² of wall, Therefore, 1 gallon can is needed.

Cost of one gallon paint = $17.00

You will spend $17.00 on paint.
