Question

using herones formula find the area of equilateral triangle with 4a with solution please now

Answer 1

Answer:

heron's formula

area of triangle = sqrt(s(s-a)(s-b)(s-c))

s= half perimeter = 4a+4a+4a /2 = 6a

Area = sqrt(6a(2a)(2a)(2a))

area = sqrt48a^4.

.

perimeter = 540

side = 180

s=270

area =sqrt(270(90)(90)(90))

=14029.26 sq cm

Answer 2

Answer:

√3/2a²

Step-by-step explanation:

The sides of triangle are a,a,a units

s=a+a+a/2

=3a/2

using herons formula

area of equilateral triangle is

√s(s-a) (s-b) (s-c)

=√3a/2×a/2×a/2×a/2

=√3/2a²
