18. What is the area of a piece of garden plot 5 yards 2 feet long by 6 yards 1 foot wide? Give your answer in square feet.

O A. 270 square feet

O B. 49 square feet

O C. 323 square feet

O D. 70 square feet

C. 323 ft²

Step-by-step explanation:

1 yard = 3 feet

5yd 2ft = (5) (3) ft + 2ft = 17ft

6yd 1ft = (6) (3) ft + 1ft = 19ft

The formula of an area of a rectangle:

A = wl

w - width

l - length

Substitute w = 19ft and l = 17ft:

A = (19) (17) = 323 ft²
