George is putting trim around his rectangular deck, including the gate. He will need 50 feet of trim to do the entire deck. If the deck is 15 feet long, how wide is the deck?

A.
8 feet
B.
25 feet
C.
10 feet
D.
20 feet

C. 10 feet

To find the width of the deck, we can use the formula for the perimeter of a rectangle:

Perimeter = 2(length) + 2(width)

Given that the deck is 15 feet long and the total trim needed is 50 feet, we can set up the equation:

50 = 2(15) + 2(width)
50 = 30 + 2(width)
20 = 2(width)
width = 10 feet

Therefore, the width of the deck is 10 feet.
