to find,

cost of white washing

first,we need to find perimeter of rectangle.

formula:

$perimeter \: of \: rectangle = 2(l + b)$

solution:

perimeter of rectangle= 2(6m+5m)

=2(11m)

=22m

.: perimeter of rectangle= 22m

cost of white washing per metre = 6.5

cost of white washing per 22m = 6.5×22m

=143.0

.:cost of white washing = Rs143
