Question

find the half of perimeter of an equilatral triangle whose area is 4 root 3 cm²​

Answer 1

Step-by-step explanation:

area of equilateral triangle

={ (√3)/4 }* side square

4√3 = { (√3)/4 }* side square

side square = 16 cm^2

side = 4 cm

half perimeter = (3*4)/2 = 6 cm

Answer 2

Answer:

area =√3/4×(s)^2

4√3=√3/4×s^2

4=s

therefore,3s=12

hence,half of it=6cm ANS
