The Total solution for NCERT class 6-12
Complete the hexagonal and star shaped rangolies (seethe given figures) by filling them with as many equilateral triangles of side 1cm as you can. Count the number of triangles in each case. Which has moretriangles?
It can be observed thathexagonal-shaped rangoli has 6 equilateral triangles in it.
Area of ΔOAB
Area of hexagonal-shaped rangoli
Star-shaped rangoli has 12equilateral triangles of side 5 cm in it.
Area of star-shaped rangoli =
Therefore,star-shaped rangoli has more equilateral triangles in it.
