Question

Find the side of a square whose area is equal to the area of a rectangle dimension are 4 CM and 9 cm​

Answer 1

Answer:

Given length of the rectangle = 9cm

Given breadth of the rectangle = 4cm

Area of the rectangle = length x breadth

⇒ 9cm x 4cm

⇒ 36cm²

Area of the square = 36cm²

Side of the square = ?

To find the side of the square, we have to substitute the values in order to find the area of the square.

⇒ Area of the square = side x side

⇒ 36cm² = s x s

⇒ 36cm² = 2s

⇒ 36 / 2 = s

⇒ 18cm = s

⇒ Side = 18cm

∴ Side of the square is 18cm.

Answer:

6 cm

Step-by-step explanation:

area of square =area of rectangle

therefore x^2 = 4×9

x^2 = 36

x=√36

x= 6

hence, the side of square is 6 cm.
