Question

A 36-m-long, 15-m-borad verandah is to be paved with stones, each measuring 6dm by 5 dm. How many stones will be required?

Answer 1

`Area of the verandah = "Length xx Breadth" = 36 xx15 = 540 m^2` Length of the stone = 6 dm = 0. 6 m

Breadth of the stone = 5 dm = 0.5 m 

Area of one stone= `0.6xx0.5=0.3m^2` 

=`540/0.3` 

= `1800` 

Thus, 1800 stones will be required to pave the verandah.
