Question

If each side of an equilateral triangle is of 36 cm then length of its medians is (1) 36 cm (2) 18 cm (3) 3613 cm (4) 1873 cm​

Answer 1

Answer:

Area of equilateral triangle =43(side)2

∴43(side)2=363

 (side)2=36×4 

               =9×4×4

               =(4×3)2

      side=12cm

perimeter =3×side

                  =3×12 

                  =36cm

Answer 2

Answer:

The length of its median is 18√3 cm.

Step-by-step explanation:

It is given that each side of an equilateral traingle is 36cm.

Let the median of triangle be x cm.

Formula to be used here:

X= √3side/2

Now putting the values

X=√3×36/2

X=√3×18

X=18√3cm.
