Question

The area of an equilateral triangle ABC in which AB =8 cm is ​

Answer 1

Answer:

The area of an equilateral triangle = √3/4 x side²

The area of an equilateral triangle = √3/4 x 8²

= √3/4 x 8 x 8

= 16√3 cm²

Answer 2

Answer:

Length of side = 8 cm

Area of eq. triangle = [$\sqrt{3}$/ 4 x $side^{2}$]

= $\sqrt{3}$ / 4 x 8 x 8 = $\sqrt{3}$ x 2 x 8

= 16 $\sqrt{3}$ $cm^{2}$
