Answer 1

Answer:

Hey There! Hope this explanation helps :)

Step-by-step explanation:

Length, breadth and height of a room are 5 m, 4 m and 3 m.

Area of four walls of the room (LSA) =2h(l+b)

=2×3(5+4)

=6(9)

=54 sq m

Area of the ceiling =l×b

=5×4

=20 sq cm.

This was only the LSA, you can calculate the TSA by adding the area of ceiling and area of floor (which is equal to the ceiling) to the LSA.
