Answer:
Length: 86 yards and width: 49 yards
Step-by-step explanation:
Rectangle A: width =50 and length=85
Perimeter = 2(50) x 2(85) = 270 yd
Area: 50 x 85 = 4,250 yd^2
Rectangle B: width: 49 and length= 86
Perimeter: 2(49) + 2(86) = 270 yd
Area: 49 x 86 = 4,214 yd^2
4,214 < 4,250
Perimeter of A = perimeter of B
