Question

I decided to add another room to the carpet buying. The last room is 3.9m by 2.2m. How much carpet do I need for all three rooms?

Answer 1

Answer:

8.58

Step-by-step explanation:

beacause the carpet is as per room size so we need to multiply 3.9×2.2m=8.58m

Answer 2

The carpet needed is 25.74 m².

Given - Dimensions of room

Find - Amount of carpet needed

Solution - The area of room is calculated by the formula-

Area = length × breadth

Keep the values in formula to find the are of one room.

Area = 3.9×2.2

Performing multiplication

Area = 8.58 m²

Now, total amount of carpet required for three rooms is -

Required carpet = 3×Area of one room

Required carpet = 3×8.58

Performing multiplication

Required carpet = 25.74 m²

Hence, the total area of carpet required is 25.74 m².
