Question

The area of four walls room is 154 metre square the length and breadth of the room are 13 and 9 respectively find the height of the room

Answer 1

Answer:

As given

Area of four walls = 154 metre square

Length = 13 m

Breadth = 9 m

Let height be h m

Then

2(l+b)× h =154 m square

2(13+9) ×h = 154

2×22×h = 154

44×h =154

h =154/44

h =7/2 = 3.5 m

Therefore height of the room is 3.5 m

I hope it is right and it helps you.

Answer 2

The height of the room is 3.5 m

Step-by-step explanation:

Length of room = 13 m

Breadth of room = 9 m

Area of 4 walls =2(l+b)h

Area of 4 walls = 2(13+9)h

We are given that The area of four walls room is 154 metre square

So,  2(13+9)h=154

22h=77

$h=\frac{77}{22}$

h=3.5

Hence the height of the room is 3.5 m
