Question

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

Answer 1

Answer:

6 cm

Step-by-step explanation:

Using,

   Area of rectangle = length x breadth

   Area of square = side^2

Let the length of side of the square be 'a'.

⇒ Area of square = area of rect.

⇒ a^2 = 4 cm x 9 cm

⇒ a^2 = 36 cm^2

⇒ a = √36cm^2

⇒ a = 6 cm

  Length of side of the square is 6 cm

Answer 2

Answer:

Area of rectangle = length x breadth

Area of square = side^2

Let the length of side of square be 'a'.

⇒ Area of square = area of rectangle

⇒ a^2 = 4 cm x 9 cm

⇒ a^2 = 36 cm^2

⇒ a = √36 cm^2

⇒ a = 6 cm

Length of side of square is 6 cm
