You want to paint the walls of your bedroom. Two walls measure 17 ft by 9 ft, and the other two walls measure 11 ft by 9 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.

Respuesta :

Answer:

$34

Explanation:

For computing the total amount spend on paint, first we have to find out the total area of walls which is shown below:

Total area of walls = 2 × (17 × 9 + 11 × 9)

                               = 2 × (153 + 99)

                              = 2 × 252

                              = 504 ft square

As we know that each gallon cover 400 ft square

So 504 ft square would cover in

= 504 ÷ 400

= 1.26 gallons

Now the total amount spend on paint is

= $17 × 2 cans

= $34
