Question

The area of equilateral triangle is 16 into 3 under root CM square find the length of each side of the triangle

Answer 1

area of triangle =16√3. if side =a
length of altitude in equilateral triangle
=(√3/2)a
area =1/2*base*altitude
16√3=1/2*a*√3/2 a
16√3=√3a^2/4. ( dividing both side by √3/4)
64=a^2. (rooting on both sides)
a=√64=8cm
