Question

A bedroom is 11.4 feet long amd 12.5 feet wide. Shui wants to paint the floor. A gallon of paint will cober approximately 150 square feet. Will one gallon of paint be enough to paint the bedroom floor with 2 coats of paint? Explain your reasoning

Answer 1

One gallon of paint is not enough to paint the bedroom floor

Explanation:

step 1

Find the area of the bedroom floor

The area is in the shape of rectangle

so

`A=(11.4)(12.5)=142.5\ ft^2`

Remember that the bedroom floor will be painted with two coats of paint

so

Multiply the area by two

`A=(2)142.5=285\ ft^2`

A gallon of paint will cover approximately 150 square feet

`285\ ft^2 > 150\ ft^2`

therefore

One gallon of paint is not enough to paint the bedroom floor
