the answer is your Rs 57.2

Answer 2

Hello mate!

The cost is :-

First you have to find the area,

Area = 2.6 X 1.1
= 2.86

Then you have to multiply it,

Cost of multiplying per Meter =Rs.20
Cost of multiplying 2.86 Meter =2.86 X 20
=Rs.57.2

This is the cost of painting one side, the question is to find for both the sides so,

Painting one side =Rs.57.2
Painting two sides =57.2 X 2
=Rs.114.4

Thank you!
