Perimeter =3 × side (as all sides of equilateral triangle are equal)
723 =3 s
723/3=s
241=s
So, side of equilateral triangle=241 cm.
Height=√3/2 ×s
= √3/2×241
=241√3 /2 cm
=208.71 cm (approx)
723 =3 s
723/3=s
241=s
So, side of equilateral triangle=241 cm.
Height=√3/2 ×s
= √3/2×241
=241√3 /2 cm
=208.71 cm (approx)
