Question

A verendah is 40 m long and 15m broad.it is to be paved with stones ,each measuring 6dm by 5dm . find the number of stone required.
​

Answer 1

l =40m

b=15 m

area of verandah[rectangle]=l*b

=40m*15m

=600m.sq

and stone each measuring 6dm by5dm

by converting it into meter we get,

0.6m by 0.5m

now, area of stone= l*b

=0.6m*0.5m

=0.3m.sq

now, number of stone required =area of verandah/area of stone

=600m.sq/0.3m.sq

=600*10/3

=6000/3

=2000. .

MERRY CHRISTMAS...
