Question

a verandas 40 m long and 15 M broad is to be pored with stones each measuring 6 metre by 5meter find the number of stones required

Answer 1

of verandah -

length = 40 .
breadth = 15

area = 40 x 15 = 600

of the stone :-

length = 6
breadth = 5

area = 5 x 6 = 30

no of stones = 600/30 = 20

Answer 2

Given length = 40m and breadth = 15m

Area = length * breadth

         = 40 * 15

         = 600m^2.


Given, Area of each stone = 6 * 5

                                             = 30m^2.


Number of stones required = 600/30

                                               = 20.


Hope this helps!
