Question

find the perimeter of square whose area is 2.25m²

Answer 1

ANSWER WITH STEPS AND FULL EXPLANATION

If the area of any square is $x$ square units, then the side of the square is of $\sqrt{x}$ units. 
Here, the area of the square is 2.25 m². 
So, the side of the square is $\sqrt{2.25 m^{2}} = 1.5 m$. 
So, the side of the square is 1.5 m. 

Now, if the side of any square is $a$ units, then the perimeter of the square is $4a$ units. 
Here, the side of the square is found to be 1.5 m. 
So, the perimeter of the square is (4 × 1.5) m = 6 m. 

∴ The perimeter of the square is 6 m.
