Question

The height of the equilateral triangle is 4cm find its area ​

Answer 1

Area of equilateral triangle = √3/4a2 = √3/4 x 42 = 4√3 cm2.

Answer 2

Answer:

A = 6.928

Step-by-step explanation:

Formula of an equilateral triangle when altitude is given

A= √3/4 x a^2

Putting given value in the formula

A = √3/4 x 4^2

A = √3/4 x 16

A = 1.732/4 x 16

A = 0.433 x 16

A = 6.928
