Answer 1

Given :

• Length of rectangular room = 5 yard
• Breadth of rectangular room = 4 yard
• Cost of Carpet = $20 per yard²

To Find :

• Total cost of Carpet for the room.

Solution :

✰ As the Carpet will occupy all the space of the room so we will find the area of the room.

⟶⠀Area of Room = Length × Breadth

⟶⠀Area of Room = (5 × 4) yard

⟶⠀Area of Room = 20yard²

Total Cost of Carpet :

⟶⠀Cost of 1 yard² × Area = Total Cost

⟶⠀20 × 20 = Total Cost

⟶⠀$400 = Total Cost

So, Total cost of Carpet required for the room is $400
