Answer:

64.5 m.

Step-by-step explanation:

We know ,

  • Area = l * b
  • 256.6 m² = 18 * b
  • b = 256.6m²/18
  • b = 14.25 m .

Perimeter ,

  • P = 2 ( l + b )
  • P = 2 ( 18 + 14.25 ) m
  • P = 2 ( 32.25 m )
  • P = 64.5 m

Solution :

Area of the rectangle = 256.6 m²

Length of the rectangle = 18 m

We know that,

Length * Breadth = Area (Rectangle)

  • 18 m * b = 256.6 m²
  • b = 256.6 m²/18 m
  • b = 14.25 m

Now, Perimeter of the rectangle :

We know that,

2( Length + breadth) = Perimeter (Rectangle)

  • 2( 18 m + 14.25) = Perimeter
  • 2 (32.25 m) = Perimeter
  • 64.5 m = perimeter
