To Find:-

• Find the cost of fencing.

Given:-

• A rectangular field having length 50 m and breadth 32 m at the rate of Rs 20 per meter.

Solution:-

$\tt \: Perimeter \: \: of \: \: rectangle = 2( l + b )$

$\tt \: Perimeter = 2( 50 + 32 )$

$\tt \: Perimeter = 2( 82 )$

$\tt \: Perimeter = 164 m$

The cost of fencing of rectangular field of 20 per meter.

$\tt \: Cost \: \: of \: \: fencing = 20 \times Perimeter \: \: of \: \: Rectangle$
