the following figure shows the floor dismensions of an L shaped room. all angles are right angles.if carpeting costs tk. 20 per square meters, what will be the cost in tk. carpeting for entire floor of the room.

Answer 1

To calculate the cost of carpeting the entire floor of the room, we need to find the area of the L-shaped room.

Let's break down the room into two rectangular sections and add their areas together.

Section 1:

Length = 7 meters
Width = 4 meters

Area of Section 1 = Length x Width = 7m x 4m = 28 square meters

Section 2:

Length = 9 meters
Width = 5 meters

Area of Section 2 = Length x Width = 9m x 5m = 45 square meters

Total Area of the L-shaped room = Area of Section 1 + Area of Section 2
= 28 square meters + 45 square meters
= 73 square meters

The total cost of carpeting the entire floor of the room would be:
Total Area x Carpeting Cost per square meter
= 73 square meters x Tk. 20/square meter
= Tk. 1460
