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
