Question

If the length and breadth of a rectangular field are 700 m and 400 m respectively, then we need of wire to fence the field.

• A. 2000 m
• B. 2400 m
• C. 2200 m
• D. 2800 m

Answer 1

The correct option is C 2200 m


To find the number of metres of wire needed to fence the field, we need to find the perimeter of the field.

Perimeter of a closed figure is the sum of lengths of all its sides.

$\therefore \text{Perimeter}=700\text{m}+400\text{m}+$
$700\text{m}+400\text{m}$
$=2200\text{m}$

Thus, we need 2200 metres of wire to fence the field.
