# The plan and measurement for a house are given in Fig. 9.67. The house is surrounded by a path 1m wide. Find the area of Living Room.

**Solution:**

The figure represents the plan and measurement for a house.

The house is surrounded by a path 1 m wide.

We have to find the area of the living room.

Area of living room = area of rectangle ACGH - area of bedroom - area of bathroom

Considering __rectangle__ ACGH,

Length = 4 + 2.5 = 6.5 m

Breadth = 3 + 3 = 6 m

Area = 6.5(6)

= 39 m²

Considering bedroom,

Length = 4 m

Breadth = 3 m

Area = 4(3)

= 12 m²

Considering bathroom,

Length = 2.5 m

Breadth = 2 m

Area = 2.5(2)

= 5 m²

Area of living room = 39 - 12 - 5

= 39 - 17

= 22 m²

Therefore, the area of the living room is 22 m².
