The perimeter = 2 length + 2 width
the length = the width +47
314 = 2*(w+47) +2w
314 = 2w +94 +2w
220 =4w
w= 220/4 = 55
l = 55+47 = 102
the length = 102 ft
the width = 55 ft
hope helped
Answer:

Step-by-step explanation:
Area of the shaded region = area of the large rectangular - area of the small rectangle
