(A) 43% (B) 30% (C) 25% (D) 15% (E) 10% Answer by privani(34) (Show Source):
You can put this solution on YOUR website! Perimeter of a rectangle = 2*width + 2*length.
Assuming length = 7, and width = 3, perimeter is:
2*7 + 2*3 = 14 + 6 = 20
Therefore, percentage of width to the perimeter is: % = 15%
Answer: (D)
