The length of a rectangular field is 7/5 its width. If the perimeter of the field is 240 meters, what is the width of the field?  Choose the most appropriate option:
A) 50 B) 60 C) 70 D) 80 E) 90
Let L be the length and W be the width. L = (7/5)W   Perimeter: 2L + 2W = 240, 2(7/5)W + 2W = 240   Solve the above equation to find: W = 50 m and L = 70 m.   correct answer 50)50
