Question

A garden has a rectangular shape whose length and width are 20 m and 11 m respectively. What's the length of the fence which surrounds the garden?

• A. $31$ meters
• B. $9$ meters
• C. $15$ meters
• D. $62$ meters

Answer 1

The correct option is D $62$ meters

Given, length of the rectangular garden = 20 m and width = 11 m.

The length of the fence of the garden is the total distance around the garden which is same as the perimeter of the garden.


Perimeter of the garden $=2\left(\text{length + width}\right)$
$=2(20+11)$
$=2\times 31$
$=62$

Hence, required length of the fence is equal to $62$ meters.
Option (d.) is the correct choice.
