Question

What is the length of the side of a square whose area is equal to the area of rectangle of sides 9 CM and 4 CM is
I. 6m
II. 6cm
III. 12 CM
Iv. None of these ​

Answer 1

Answer:

(iv) None of this.

Step-by-step explanation:

Area of rectangle

= l×b

= 9×4

=36

Area of the rectangle is = the area of square.

Area of square = 36

Formula for Area of square (s×s)

Here, it means s^2.

${6}^{2} = 36$

Hence, the length of the side of the square measures 6 cm.

(correct me if I'm wrong)

Answer 2

Given :

⬤ Area of square is equals to the Area of Rectangle .

⬤ Length of Rectangle is 9 cm .

⬤ Breadth of Rectangle is 4 cm.

To Find :

⬤ Length of the Side of a Square .

Solution :

As given that , Find the Length of Square whose area is equals to the Area of Rectangle . Hence ,

• Length = 9 cm .
• Breadth = 4 cm .

Now :

Area of Square = Area of Rectangle

(Side)² = length × breadth

Side² = 9 × 4

Side² = 36

Side = √36

$\sf{Side = 6}$

Therefore , The Length of Side of Square is 6 cm .

Option II. 6 cm is Correct .
