_________Here's your Answer..______
Given;
Length = 7.5 m
Breadth = 3.5 m
Now,
Area of 4 walls = 2 ( l + b) × h
=> 77 = 2 ( 7.5 + 3.5) × h
=> 77 = 2 × 11 × h
=> h = 77 ÷ 22
=> h = 3.5 m.

area of 4wall of room=77m^2
let the length be l
lbh=area
l*7.5*3.5=77
l=77/7.5*3.5=2.93m
let the length be l
lbh=area
l*7.5*3.5=77
l=77/7.5*3.5=2.93m
