Solution

Given length of rectangle $= 20 m$
breadth of rectangle $= 15 m$
The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape.
Perimeter of rectangle $= 2 (l + b)$
$= 2 (20 + 15) = 2 (35) = 70 m$
Hence, the length of the iron wire required to fence a ground is $70 m$ .
