ABC is an equilateral triangle of side 2 cm. With A, B, C as centre and radius 1 cm three arcs are drawn. The area of the region within the triangle bounded by the three arcs is

Using Rule 17,

Each angle of the triangle = 60°
Required area of the three sectors

= 3 ×	60	× π(i)²
	360

=	π	cm²
	2

Area of triangle =	√3	× 4 = √3cm²
	4

∴ Required area =		√3 -	π		cm²
			2

	3√3 -	π		cm²
		2
