Important Terms about Class 8 Maths Chapter 11

A flooring tile has the shape of a parallelogram whose base is 24 cm and the corresponding height is 10 cm. How many such tiles are required to cover a floor of area 1080 m^2? [If required you can split the tiles in whatever way you want to fill up the corners]

Base of flooring tile = 24 cm = 0.24 m
Corresponding height of a flooring tile = 10 cm = 0.10 m
Now
Area of flooring tile = Base x Altitude
= 0.24 x 0.10
= 0.024 m^2

Number of tiles required to cover the floor
= Area of Floor/Area of one tile
= 1080/0.024
= 45000 tiles
Hence 45000 tiles are required to cover the floor.

Find the area of a rhombus whose side is 6 cm and whose altitude is 4 cm. If one of the diagonals is 8 cm long, find the length of the other diagonal.

Since rhombus is also a kind of parallelogram.
Area of rhombus = Base x Altitude = 6 x 4 = 24 cm^2
Also, Area of rhombus = 1/2 x d1 x d2
According to question,
24 = 1/2 x 8 x d2
So, 4d2 = 24 and d2 = 6 cm
Hence, the length of the other diagonal is 6 cm.

In 8th Maths NCERT Chapter 11 Mensuration, we have to find the Areas, Perimeter, missing dimensions of the geometrical figures. Area of triangle, square, parallelogram, trapezium on the basis of given information and applying simple formula. Area of various specific quadrilateral like parallelogram, rhombus, rectangle, square and general quadrilateral in which we divide the quadrilateral into two triangles and then find the area of triangles and add them. Similarly we can find the area of polygon by dividing it into triangles and adding the areas of all triangles. Surface area and volumes of solid figures like Cube, Cuboids, Cylinders, Cones, etc. are given to find one the basis of application of formulae.
