Answer 1

Answer:

4500rs

Step-by-step explanation:

Glass dimensions is of rectangular shape

Therefore length(l) =4m

Breadth(b) =3m

Area require for cleaning

=area of rectangel = lxb

=4x3= 12m square

Hence there are 15 glass

There fore area of 15 glass dimensions =15x12

=180 m sq

But the glass should be clean from both the side

Are for cleaning the glass from both the side=180x2=360m square

Therefore cost of cleaning 1 sq m =12.50

Therefore cost of cleaning 360 sq m=360x12.50=4500rs
