Question

The area of four walls of a room is 51 if the room is 5m long and 3.5m wide find the height of the room

Answer 1

Area of four walls = LSA of room = 2 * h * (l+b) sq units

lenth=5m breadth = 3.2m,

Area of four walls = 2 *h * (5+3.2)

2*h*8.2=57.4m2

h=57.4/2*8.2

h=57.4/16.4

h=3.5 m

Cheers!

Answer 2

Solutions :-

Given :

The area of four walls of the room is 51 cm².

And the room is 5 m long and 3.5m wide.

Find the height of the room :-

We know that,

Curved surface area of cuboid = 2h (l + b)

=> 51 = 2h (5 + 3.5)

=> 51 = 2h × 8.5

=> 51 = 17h

=> 51/17 = h = 3

Hence,

The height of the Room = 3 m
