Step-by-step explanation:
Given, perimeter of equilateral triangle is 60cm.
Perimeter of equilateral triangle=60cm
3× side =60
∴ side = 3/60 =20cm.
Area of equilateral triangle = √3 × (side)²/4
= √3 × 20²/4
=100√3 cm²
=173.2cm
Height of equilateral triangle = √3(side)²/2
=√3×20/2. =10√3cm
= 17.32 cm
