Q2 of 24 Page 143

Find the area of four walls of a room whose length 3.5 m, breadth 2.5m, and height 3 m.

Given: Length (l) = 3.5m

Breadth (b) = 2.5m


Height (h) = 3m


As we know, the room is in cuboid shape.


So, Area of Four walls = Lateral Surface Area of Cuboid = 2h (l + b)


= 2 × 3 (3.5 + 2.5)


= 6 (6)


= 36m2
