The length of a rectangular field is 7/5 its width. If the perimeter of the field is 432 meters, what is the width of the field? Choose the correct answer
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 = 432, 2(7/5)W + 2W = 432   Solve the above equation to find: W = 90 m and L = 126 m.   correct answer 90)90
