Question

The area of a square of side 9 cm is the same as that of the rectangle of length 27 cm. What is the breadth of the rectangle?​

Answer 1

Answer:

Step-by-step explanation:

Area of square = Area of rectangle.

a² = l × b

a= side of square = 9cm

l= length of rectangle = 27cm

b = breadth of rectangle

(9)²= 27b ⇒b= 81/27⇒ b=3cm

Answer 2

Given:

Area of square = Area of rectangle

Side of square = 9cm

Length of rectangle = 27cm

To Find:

Breadth of the rectangle

Solution:

Now,

Area of square = (side)²

= (9)²

= 81cm²

We know that,

Area of square = Area of rectangle = 81cm²

So,

Area of rectangle = l × b

81cm² = 27 × b

81/27 = b

3 = b

Hence, the breadth is 3cm
