Question

A floor 20 meters long and 15 meters broad is to be paved with rhombus shaped tiles whose diagnols are 30 meters and 40 meters. Find the number of tiles requried

Answer 1

Step-by-step explanation:

First find the area of the floor

Area of rectangle = Length * Breadth

= 20*15

= 300 sq. metres

Now we have to find the area of each tile

Area of rhombus=(first diagonal+second diagonal)/2

= (30+40)/2

=(70)/2

=35 sq.metres

Total tiles required=Area of floor/Area of each tile

=300/35

=8.57142714271427142......
