Question

If the area of a square is equal to the area of a rectangle having sides of length 9 cm and 3 cm, then the length of each side of the square is :
(A) 3 cm (B) 9 cm (C) 27 cm (D) 81 cm
(Imdad Uddin Mazumder)

Answer 1

Length of each side of square is 5.2 cm.

Step-by-step explanation:

Since we have given that

Area of square = Area of rectangle.

Since length of rectangle = 9 cm

Breadth of rectangle = 3 cm

So, Area of rectangle would be

$Length\times breadth \\\\=9\times 3\\\\=27$

So, Area of square = 27 sq. cm

So, we can rewrite it as :

$Side^2=27\\\\Side=\sqrt{27}=3\sqrt{3}=5.2\ cm$

Hence, length of each side of square is 5.2 cm.
