Answer 2

hello users ..........

_______________________________________________

we have given that :
length of path = 105 m 
and 
breadth of path = 4.5 m 
and,
length and breadth of brick are 24 cm and 15 cm respectively. 

we have to find :
no of bricks required ??

solution:-
we know that :-
area of rectangle = L * B 
where L is length and B is breadth of rectangle,

Here;
area of rectangular path = 105 * 4.5 = 472.5 m²

and 
area of rectangular brick = 24 * 15 = 360 cm² = 0.036 m²

Hence;
No. of bricks required = Area of rectangular Path / Area of one brick 

= 472.5 / 0.036 
= 13125 bricks Answer
