Answer 2

Answer:

• The area of the wall is 108 sq. m.
• And the cost of the carpet is ₹5400.

Step-by-step explanation:

Given: If Length of wall = 12 m and

breadth = 9m  

Find the area of a wall.

Formula Area of rectangle = length × breadth

Step 1: Find the area of a wall by using the area of the rectangle.

The area of a wall=  length × breadth

= 12 × 9

= 108 sq. m

So, the area of the wall is 108 sq. m.

Step 2: If the cost of carpet ₹50 per sq. m. then find the cost of the carpet.

The cost of carpet = 50 ×  108 =  ₹5400  

So, the cost of the carpet is ₹5400 .
