Step-by-step explanation:
Let side of triangle be a
Height=[ (a^2— a^2/4)]^1/2 = (3a^2/4)^1/2 = a/2×3^1/2
Area= a^2/4×3^1/2=3^1/2
a^2=4
a=2
Perimeter=6

Step-by-step explanation:
The formula for the area of an equilateral triangle is (a**2 * sqrt(3))/4, where a is the side of the triangle. So:
sqrt(3) = (a**2* sqrt(3))/4.
divide both sides by sqrt(3):
1 = a**2/4
a**2 = 4, so
a = 2
the perimeter = 3a =6
Hope it helps Buddy..
