Answer 2

cost of papering = $24960

Step-by-step explanation:

given data

wide B = 6 m

high H = 4 m

paper wide = 80 cm

cost = Rs 120 per piece of 5 m²

solution

first we get here  surface area of the room that is

surface area of the room = 2 × (L×B + B×H + H×L)    ...................1

put here value and we get

surface area = 2 ×  $(8\times 6+6\times 4+4\times 8)$

surface area = 208 m²

and cost of papering is

cost of papering = 208 × 120

cost of papering = $24960
