híñt :- 16558.50 rupees..
explain it​

Answer 1

Answer:

$\huge{ \underline{ \underline{\bf{ \purple{RequiredAnswer}}}}}$

• Length of the room = 3.8 m

• Breadth of the room = 4.5 m

• Height of the room = 3.5 m

Area of longer wall = 3.8 m × 4.5 m

= 17.1 square meters

There are 2 longer walls. So the total area of the longer walls is 17.1 + 17.1 = 34.2 square meters.

Area of shorter wall: 4.5 × 3.5 m

= 15.75 square meters

Again, there are 2 shorter walls. So the total area of the shorter walls is 15.75 + 15.75 = 31.5 square meters.

Add up the individual areas to get = 34.2 m² + 31.5 m²

= 65.7 m²

cost of 1 m² = 250 rupees

cost of 65.7 m² = 65.7 × 250 rupees

=16425 rupees

Answer 2

Answer:

Length of the room = 3.8 m

Breadth of the room = 4.5 m

Height of the room = 3.5 m

Area of longer wall = 3.8 m × 4.5 m

= 17.1 square meters

There are 2 longer walls. So the total area of the longer walls is 17.1 + 17.1 = 34.2 square meters.

Area of shorter wall: 4.5 × 3.5 m

= 15.75 square meters

Again, there are 2 shorter walls. So the total area of the shorter walls is 15.75 + 15.75 = 31.5 square meters.

Add up the individual areas to get = 34.2 m² + 31.5 m²

= 65.7 m²

cost of 1 m² = 250 rupees

cost of 65.7 m² = 65.7 × 250 rupees

= 16425 rupees
