Question

find the area of a triangle whole sides are 6cm,6cm and 6cm​

Answer 1

Since all sides are equal.

Hence , it is an equilateral triangle.

We know that

Area of equilateral ∆ = √3/4 × (side)²

→ √3/4 × 6²

→ √3/4 × 36

→ √3 × 9

→ 9√3 cm² ans...

Answer 2

area of equilateral triangle=root3×(side)^2/4

=root3×6^2/4

=root3×36/4

=root3×9

=9root3cm^2
