  Question

# 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

Solution

## 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  Suggest corrections
