A flooring tile has the shape of a parallegrom whos base is 24 cm and the corresponding height is 10 cm . How many such tiles are required to cover a floor of area 1080msquare
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.
a rectangle, square, a rhombus, a parallelogram, a trapezium.
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.
Given : base= 24 cm
Height= 20 cm
Area of floor= 1080 m²= 1080×100×100cm²
Area of the Parallelogram = base x
= 24 x 10 = 240 cm²
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
