Question

4. Find the area of a equilateral triangle whose sidene
a =2cm​

Answer 1

Step-by-step explanation:

Area of equilateral triangle = root 3/4a2= root 3/4*(2)2=root3/4*4= root3

Answer 2

Answer:

Step-by-step explanation:

Area of equilateral triangle = √3 a²

                                                  4

Here : a = 2cm

√3 x 2²

4  

       

√3 x 4

4          

cancel 4 and 4

SO THE AREA OF EQUILATERAL TRIANGLEWHOS SIDE IS 4CM IS √3 CM²
