Question

What in the area of an equilateral triangle with side 2 cm?​

Answer 1

Answer:

Side = 2 cm

Area of equilateral triangle =

$\sqrt{3} \div 4 \times {side}^{2} \\ = \sqrt{3} \div 4 \times {2}^{2} \\ = 1.73 \div 4 \times 4 \\ = 1.73 \: {cm}^{2}$

Answer 2

$\textrm{Area of an Equilateral Triangle = }\rm{\dfrac{\sqrt{3}}{4} \times Side^{2}}$

$\to\textrm{Area of an Equilateral Triangle = }\rm{\dfrac{\sqrt{3}}{4} \times (2 cm)^{2}}$

$\to\textrm{Area of an Equilateral Triangle = }\rm{\dfrac{\sqrt{3}}{4} \times 4 cm^{2}}$

$\to\textrm{Area of an Equilateral Triangle = }\rm{\sqrt{3}\times 1cm^{2}}$

$\to\textrm{Area of an Equilateral Triangle = }\rm{\sqrt{3}\times cm^{2}}$

$\to\textrm{Area of an Equilateral Triangle = }\rm{\sqrt{3}cm^{2}}$
