Question

If the perimeter of a square field is 400 m, what is the length of each side of the field?

• A. $100m$
• B. $50m$
• C. $150m$
• D. $200m$

Answer 1

The correct option is A $100m$

Given: Perimeter of the square field = 400 m
To find: Length of its side

We know that the perimeter of a square of side 'a' is given by 4a.
Let the length of the side of the square field be $l$ m.
Then, $4l=400$
$⟹l=\frac{400}{4}=100m$
