Answer:
Length of room = 5m
Breadth of room = 4m
Height of room = 2m
Area of four walls of room = Lateral surface area of room = 2 ( l + b ) h = 2 ( 5 +4 ) × 2
= 4 × 9 = 36 metre square
Answer:
HEY MATE HERE'S YOUR ANSWER!
Length(l) of room = 5m
Breadth(b) of room = 4m
Height(h) of room = 2m
•°• Area of 4 walls of room = Curved Surface Area of Room
= 2( lh + bh)
= 2(l+b) × h
= Perimeter of base × height
= (5+4+5+4 ) × 2
= 18 × 2 m²
= 36 m²
Thus the area of 4 walls of room is 36m².
