Solution

Finding the perimeter of rectangle :
Length of rectangle $=$ $1.3 k m$ $= 1.3 \times 1000 m = 1300 m$
Breadth of rectangle $=$ $800 m$
Perimeter of the rectangle $= 2 (l + b)$
$= 2 (1300 + 800) m = 2 \times 2100 m = 4200 m o r 4.2 m$
Therefore, the perimeter of the rectangle $4200 m o r 4.2 m$ .
