Question

a floor 20m long and 15m broad is to be paved with rhombus shaped tiles whose diagonals are 30cm and 40cm. Find the number of tiles required

Answer 1

Answer:

Given below are the dimensions of floor,

Length =40 m.

Breadth =15 m.

We know that,

Area =l×b = 40×15 = 600m

2

.

Here the length of one tile =60 cm =6/10 m.

Breadth of one tile =50 cm =5/10 m.

So the area of one tile =0.6×0.5=0.30 = 3/10 m

2

We know that,

Let A

1

and A

2

be the area of floor and a tile respectively

Number of tiles =

A

A

1

Substituting the values,

Number of tiles =

0.3

600

=2000

Answer 2

Answer:

No of tiles required=5000 pic
