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.
