A rectangle has a perimeter of 36 meters and a width of 6 meters. Find the length of the rectangle.

(A) 6 meters

(B) 8 meters

(C) 10 meters

(D) 12 meters

Answer: (D) 12 meters

Solution:

Perimeter = 2(length + width)

36 = 2(length + 6)

36 – 12 = 2(length)

24 / 2 = length

Length = 12 meters
