Question

a rectangular Courtyard is 20 m 16 cm long and 15 m 60 cm broad.It is to be paved with square stones of the same size find the least possible number of such stone

Answer 1

first convert L and B
into m

i.e., L = 20.16 m

B = 15.60 m




Area of rectangular courtyard
= L × B

=( 20.16 × 15.60 )

=314.496 m^2



now let the dimension of the the stone (smallest) = 1 × 1



then ,

no. of stones
=(area of courtyard in cm)/(area of stone)


(convert 314.496 m^2 into cm ^2

e.i =314.496 ×100×100
=3144960 cm^2)


= ( 3144960 )/( 1×1 )

= 3144960



hence no. of least stones is 3144960





hope it will be helpful to you....
