Question

plz solve this sum for me plz plz

Answer 1

1. area of door = lb=2 * 1=2m sq.
2 area of wall = 4.5*3.6=16.2m sq.
Door will be not whitewashed so ,
ar. of wall -ar. of door = ar. of wall to be whitewashed
so,
16.2-2=14.2m sq.
•rate of white washing per sq. m=20
•rate of white washing 14.2 m sq. =20rs*14.2
=284rs
