Question

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

Answer 1

From the question it is given that,

Length of rectangular lawn = 10m

Width of rectangular lawn = 4m

Then,

Perimeter of fencing = length of fencing

Perimeter of fencing = two smaller sides + one longer side – gap in the longer side

= 4 + 4 + 10 – 1

= 18 – 1

= 17 m

Therefore, length of fencing is 17 m.
