Question

find the area of the four walls of a room if its height is 10cm and perimeter of the floor is 10m​

Answer 1

Answer:

1 m²

Step-by-step explanation:

we know that lateral surface area of cuboid is

2(l+b)*h

that is simply perimeter of floor into height

=0.10*10²

=1 m²

Answer 2

We know that perimeter of floor =2(l+b) unit.

Perimeter of floor =10m=1000cm

Height=10cm

We know that area of four walls =2(l+b)h

=1000cm* 10cm

=10000cm^2 Ans
