Question

the Length breadth and height of a room are 8 metre 6.5 metre 3.5 metre find the area of four walls of the room and the area of the floor of the room
​

Answer 1

Answer:

Area of 4 walls = LSA of Cuboid

= 2h(l + b)

=2 X 3.5 ( 8 + 6.5)

= 7 x 14.5

=101.5 meter sq

_____

Area of Floor = area of rectangle

= L x B

= 8 x 6.5

= 52 SQ Metre.

Answer 2

Step-by-step explanation:

Given that,

Length of the Room (l) = 8 m

Breadth of the Room (b) = 6.5 m

Height of the Room (h) = 3.5 m

_____________________

Area of four walls of the room =2*(lb + bh) sq.unit

=2*(8*3.5 + 6.5*3.5) m²

=2*(28 + 22.75) m²

= 101.5 m²

Area of four walls of the room = 101.5 m²

______________________

Area of the floor of the room = length x breadth sq.unit

= 8*6.5 m²

=52 m²

Area of the floor of the room = 52 m²
