Answer :

It can be observed that hexagonal-shaped rangoli has 6 equilateral triangles in it

Area of = (Side)^{2}

= (5)^{2}

= x 25

= cm^{2}

Area of hexagonal shaped rangoli = 6 x

= cm^{2}

Area of equilateral triangle having its side as 1 cm = (1)^{2}

= cm^{2}

Number of equilateral triangle of 1 cm side that can be filed in this hexagonal shaped rangoli = = 150

Star shaped rangoli has 12 equilateral triangles of side 5 cm in it

Area of star shaped rangoli = 12 * * (5)^{2}

= 75

Number of equilateral triangles of 1 cm side that can b e filled in this star shaped rangoli =

= 300

Therefore, star shaped rangoli has more equilateral triangles in it
