Answers
Answer:
area of 4 walls=101.5 m^2 area of floor=52 m^2
Step-by-step explanation:
area of 4 walls=2(l+b)*h
=2(8+6.5)*3.5
=2(14.5)*3.5
=101.5 m^2
area of floor=l*b
=8*6.5
=52 m^2

The length, breadth and height of a room are 8 m, 6.5 m and 3.5 m respectively. Find the area of 4 walls of the room and the area of the floor.
║⊕ANSWER⊕║
GIVEN
Length = 8 m
Breadth = 6.5 m
Height = 3.5 m
Area of the 4 walls = 2h(b+l)
= 2 * 3.5 (8 + 6.5)
= 101.5 m²
Area of the floor of the room = length × breadth
= 8 × 6.5 m²
= 52 m²
