Answer :

Given area of the square = 4. cm2

We know that area of the square = × d2


d is the diagonal of the square


× d2 = 4.


d2 = 9


d = 3 cm


diagonal of the square = 3 cm


step – 1:


Draw the a horizonal line with the starting point as A and draw 45o ray from point A.


(It is a square so, the angle between side and diagonal will be 90o)



Step – 2:


We know the length of diagonal, so cut the ray with 3 cm arc



Step – 3:


Connect the intersecting point with horizontal line and name the intersection point as O



The above fig. forms a right-angle triangle


Sin 45o =



BO =


In square all sides are equal we can draw rest of the fig. with the same measurement.



Thus, a square can be drawn when its area is given.
