Question

What in the area of an equilatural triangle with side 2 CM?​

Answer 1

Answer:

We know

Area of An Equilateral Triangle=

$\frac{ \sqrt{3} {a}^{2} }{4}$

here given the side is 2cm

therefore, substitute the value

that is

$\frac{ \sqrt{3} \times {2}^{2} }{4} \\ \frac{ \sqrt{3} \times 4}{4} \\ = \sqrt{3}$

therefore the Area of The Triangle is

√3 cm²

Answer 2

Answer:

Given : Side of equilateral triangle is 2 cm

We know that in equilateral triangle ,all sides of

triangle are equal.

So, therefore a=2cm

√3=1.73

Area of ∆ equilateral triangle=√3 /4×a2

=√3/4×2to the power 2

=√3/4×4

=√3

=1.73 cm2

I hope this may help you dear...
