Daniel needed to paint his patio, so he made a scale drawing of it. He knows that the width of the patio is 10 feet, but the scale drawing is in inches. Homework Help ✎ Find the length of the patio in feet.

Find the area of the patio so Daniel knows how much area he needs to paint.

One can of paint covers 125 square feet. How many cans of paint will Daniel need to buy?

Find the ratio between two corresponding sides and use it to create a proportion or to multiply as a scale factor and find the missing length.

*x* = 17.5 feet

Use the answer that you got for part (a) to find the area of the patio.

Patio Area: 175 square feet

If each can of paint covers 125 square feet, how many cans are needed to cover 175 square feet?

Daniel is only able to buy full cans of paint. Round up the cans of paint if it does not come out to a whole number.
