20 m4. A flooring tile has the shape of a parallelogram whose base is 24 cm and thecorresponding height is 10 cm. How many such tiles are required to cover a floor Oarea 1080 m2? (If required you can split the tiles in whatever way you want to fill upthe corners).attered on the floor. |

Answer» Mensuration: Mensuration is the branch of mathematicswhich concerns itself with the measurement of Lengths, areas & volume ofdifferent geometrical shapes or figures. Plane Figure: A figure which lies in aplane 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 isthe total length of the curve. Unit of perimeter is a unit of length. Area: the area of the plane figure is thesurface enclose by its boundary. A square centimetre (cm²) is generallytaken at the standard unit of an area. We use square metre (m²) also for theunits 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 xheight = 24 x 10 = 240 cm² Area of1 tile = 240 cm² [Tiles are in the shape of a parallelogram] Number of tiles required= Area of theFloor/Area of the Tiles = 1080 X100 X100/240 =45000 Number of tiles required to cover a Floor=45000 ========================================================= |
