Question

1.- A flooring tile is in the shape of parallelogram where
bas is 20cm and corresponding height & 15 cm. how
many such tiles are required to cover
floor of area
58,500 m² ​

Answer 1

Answer:

Mensuration:

Mensuration is the branch of mathematics which concerns itself with the measurement of Lengths, areas & volume of different geometrical shapes or figures.

Plane Figure: A figure which lies in a plane is called a plane figure.

For e.g:  a rectangle, square, a rhombus, a parallelogram, a trapezium.

 

Perimeter:

The perimeter of a closed plane curve is the total length of the curve.

Unit of perimeter is a unit of length.

Area: the area of the plane figure is the surface enclose by its boundary.

A square centimetre (cm²) is generally taken at the standard unit of an area. We use square metre (m²) also for the units of area.

==========================================================

Solution:

Given : base= 24 cm

Height= 20 cm

Area of floor= 1080 m²= 1080×100×100cm²

[1m²= 10000cm²]

Area of the Parallelogram = base x height

= 24 x 10 = 240 cm²

Area of  1 tile = 240 cm²

[Tiles are in the shape of a parallelogram]

 Number of tiles required= Area of the Floor/Area of the Tiles

= 1080 X100 X100/240  =45000

Number of tiles required to cover a Floor= 45000

Hope this will help you...

Step-by-step explanation:

Answer 2

19,500 tiles

Step-by-step explanation:

Base = 20 CM

Height = 15 CM

Area of parallelogram = B × H

= 20 × 15

= 300 CM²

Area of Floor = 58,500 m²

1 M ² = 100 CM ²

58,500 m² = 58,50,000 CM²

Tiles required to cover area =

$\frac{5850000}{300} \\ = 19,500 \: tiles$
