The scale drawing of a deck that Mr. Ford is building measures 15 cm by 21 cm. Each 3 cm on the scale drawing equals 5 feet. What are the actual dimensions of the deck?

Answer 1

To find the actual dimensions of the deck, we first need to find the scale factor between the scale drawing and the actual dimensions.

Given that each 3 cm on the scale drawing equals 5 feet, we can calculate the scale factor as follows:

Scale factor = 5 feet / 3 cm = 5/3

Now, we can find the actual dimensions of the deck by multiplying the dimensions of the scale drawing by the scale factor:

Actual length = 21 cm * (5/3) = 35 feet
Actual width = 15 cm * (5/3) = 25 feet

Therefore, the actual dimensions of the deck that Mr. Ford is building are 35 feet by 25 feet.
