Width: x
Length:  2x + 8
Perimeter: 112 meters

Perimeter = 2(Length) + 2(width)

Equation: 
2 (x) + 2 (2x + 8) = 112
2x + 4x + 16 = 112
6x = 112 - 16
6x/6 = 96/6
x = 16

Dimensions:
Width: x = 16 meters
Length: 2(16) + 8 = 40 meters

Area of rectangle = Length × Width
Area = (40 meters) (16 meters)
Area = 640 m²

Answer: The area is 640 m².
