Answer 1

Answer:

78rs

Step-by-step explanation:

length of a pool = 20m

breath of a pool = 15m

depth of a pool = 2cm = 0.02m

therefore the area of the pool = l*b*h                          

                                                   = 20*15*0.02

                                                   =6m^2

the total amt for cementing its floor = 6*13

                                                           =78rs
