Answer 2

What is Perimeter?

The word perimeter is derived from two Greek words peri meaning around and metron

meaning measure.

Thus, we measure the perimeter of a plane figure by adding the lengths of its sides. Perimeter is the distance around a plane figure or the length of the boundary of a plane figure.

Observe the following examples.

• If the rectangular park is of 150 m length and 80 m width, then
• Distance jogged by Aditya everyday = 4 x perimeter of the park

= 4 x (150 + 80 + 150 + 80) m

= 4 x (460) = 1840 m

• If each side of the square handkerchief is 10 cm, then lace required by Mrs Saini = Perimeter of the handkerchief = 10 + 10 + 10 + 10 cm = 40 cm
