. Find the height and area of an equilateral triangle whose side is a cm.(Use Heron'sformula)

If perimeter of a triangle is x cm and its sides are p,q and r cm. what will be the area of triangle ? Use the heron's formula.

A traffic signal board, indicating 'SCHOOL AHEAD' , is an equilateral triangle with side a. Find the area of the signal board, using Heron's formula. If its perimeter is 180 cm, what will be the area of the signal board?

Equilateral triangles I,Ill and IV are such that the altitude of triangle I is the side of triangle II,the altitude of triangle II is the side of triangle and the altitude of the triangle is the side of triangle IV.If the area of triangle I is 2cm^(2), then the area (incm ) of triangle IV is:
