Question

26. The perimeter of the floor of a room
is 18 m. What is the area of four
walls of the room, if its height is
3m​

Answer 1

now given, perimeter of floor of room = 18m (we dont know if each side is equal or not).

height of room = 3m

so, if we stretch the four walls onto a flat plane, we get a large rectangle with dimensions 18m x 3m.

thus the area of 4 walls = area of the rectangle = 18 x 3 = 54$m^2$

pls mark as brainliest

Answer 2

Answer:

54m²

Step-by-step explanation:

the area of four walls= perimeter X hieght

= (18 X 3)m²

= 54m²
