The perimeter of an equilateral triangle is equal to the circumference of a circle. The ratio of their areas is (Use π = 22/7)

Using Rule 6,
Side of the equilateral triangle = x units (let)
According to the question, 3x = 2πr

⇒ x =	2	πr
	3

∴ Area of equilateral triangle

=	√3	× side²
	4

=	√3	×		2	πr		²
	4			3

=	√3	×	4	π² r²
	4		9

=	π² r²	sq. units
	3√3

∴ Required ratio =	π² r²	: π r²
	3√3

= π = 3√3

=	22	: 3√3 = 22 : 21√3
