424. House Paint April wants to paint the exterior of her house. One gallon of paint covers about 350 square feet, and the exterior of the house measures approximately 2000 square feet. How many gallons of paint will she have to buy?

Answer 1

If the exterior of the house is 2000 square feet and each gallon of paint covers 350 square feet.

Then she needs to buy 6 gallons of paint.

Explanation:

Dividing the total area by the area that each gallon of paint covers we get,

`$(2000)/(350) * (50)/(50)=(40)/(7)$$`

Now, performing long division we get,

`$7\overset{5}{\overline{\left){\begin{align} & 40 \\ & \underline{35} \\ & \underline{05} \\ \end{align}}\right.}}$$`

She needs five gallons of paint fully and some amount of the sixth gallon because we get a remainder.

She can't buy paint in fraction, hence she has to buy 6 gallons of paint.
