There is a rectangular lawn 10m long and 4m wide in front of Meena’s house (Fig. 6.12). It is fenced along the two smaller sides and onelonger side leaving a gap of 1m for the entrance. Find the length of fencing

The perimeter of the fencing will give us the length of fencing.

The lawn is fenced only on three sides.

Two smaller sides and one longer side.

Perimeter = 4 + 4 + 10 – 1

Perimeter = 17 m

Therefore the length of fencing = 17 m.
