Answer 1

Here is your solutions

Given :-

The area of the 4 walls of a room is 77 m^2

length = 7.5 m

Breadth = 3.5 m

To find the height of 4 wall :-

We know that

Area of 4 wall = 2 (l+b) × h

77 = 2 (7.5+3.5) × h

77 = 2× 11 × h

77 = 22 × h

h = 77/22 m

h = 3.5m

Hence ,

The height of 4 wall room is 3.5m
