Question

find out the area of equilateral triangle, with side a​

Answer 1

Step-by-step explanation:

Area of equilateral triangle= 1/2 × a × b × sin(angle)

All angles and sides are equal in an equikateral triangle, so

=> 1/2 × a × a × sin(60)

=> 1/2 × a^2 × √3/2

=> √3/4 × a^2

Add the unit if it's mentioned

(must be in terms of a)
