Answer 2

Answer:

Measure of a door is 2.6m by 1.1m.

Area of a rectangle is

A = length x width

Area of one side of door is

A= 2.6 x 1.1

A= 2.86

Area of both sides of door is

A= 2 x 2.86 = 5.72

The area of both sides of the door is 5.72 m²

It is given that the cost of painting both sides of the door at the rate if RS 20 per square meter.

5.72 x 20 = 114.4

Therefore, the cost of painting both sides of the door is Rs. 114.40.
