Question

The area of a square shaped field is 3,60,000 square metres. Find the perimeter of the field.

• A. 1800 m
• B. 2400 m
• C. 2800 m
• D. 3200 m

Answer 1

The correct option is B 2400 m

Let the length of each side of the square shaped field be a.
=> Area of the field = <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $a^2$

So, a × a = 360000 $m^2$
=> a × a = 600 x 600 $m^2$
=> a = 600 m

So, the length of each side of the square shaped field is 600 m.

Perimeter of the field = 4a = 4 × 600 = 2400 m
Therefore, perimeter of the square shaped field is 2400 m.
