AcademicMathematicsNCERTClass 7

Given :

Perimeter of a square $= 320 m$.

To find :

We have to find the area of the square.

Solution :

Perimeter of a square of side \'s\' is 4s.

$ 4a = 320 m$      (Where a is the side length of the square)

$a = \frac{320}{4} m$

$a = 80 m$


$$Area of a square = a^2$$

Area of a square $= (80)^2  m^2$

Area of a square $= 6400  m^2$.

Therefore, the area of the square is $6400 m^2$.
