Question

The side of an equilateral triangle of area 63root3 cm² is​

Answer 1

Answer:

Let the side of the equilateral triangle be a cm

We know that area of an equilateral triangle =

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

area of the triangle

$\frac{ \sqrt{3} }{4} {a }^{2} = 63 \sqrt{3} \\ {a }^{2} = \frac{4 \times 63 \times \sqrt{3} }{ \sqrt{3} } \\ {a }^{2} = 256 \\ a = 16$

Side = 16cm
