Answer 1

Answer:

$4050

Step-by-step explanation:

Length= 5m, breadth= 4m, height= 3m.

Area Of 4 walls of a room= 2*h*(l+b)

                                          =2*3*(5+4)m square.

                                          =6*9=54m square.

Whitewashing 1m2 requires= $7.50

therefore, White washing 54m2 requires=$7.50 *54=$4050 is the answer.
