Answer 1

Given:

There are 3000 rhombus shaped tiles

The rhombus shaped tiles have diagonal 45 cm and the length of rhombus is 30 cm

To find :

The area of the floor and the cost of poilishing the floor

solution:

let us take two triangle from the rhombus,

according to the heron's formula

(30+30+45)/2

=105/2

=52.5 cm

the area of the triangle is

Square root of {(52.5-30)(52.5-30)(52.5-45)}

=22.5 and square root of (7.5)

There for the area of the rhombus =2(22.5) and square of(7.5)

=45 and spuare root of (7.5)
