Question

A room is 8m long,7.6m wide and 3.5 m high. The walls are to be distempered , allowing 25 m^2for doors, windows etc . Find the total area to be distempered.

Answer 1

Answer:

area of four walls = (8+7.6+8+7.6)*3.5)

=109.2. Total area to be distempered = 109.2-25.0=84.2 or 84 m

Answer 2

The total area to be distempered is 90.4 m².

Given:

Length of the room = 8 m

Width of the room = 7.6 m

Height of the room = 3.5 m

Area of the doors and windows = 25 m²

To Find:

We need to find the total area to be distempered.

Solution:

Total area of the room = (8 × 7.6) + (7.6 × 3.5) + (3.5 × 8)

= 115.4

Now, the area to be distempered = area of the room - area covered by the doors and windows

= 115.4 - 25

= 90.4

Thus, the total area to be distempered is 90.4 m².
