Question

find the side of an equilateral triangle measure 9* root (3). find its area ??

Answer 1

HELLO DEAR,

I THINK SOMETHING IS MISTAKE IN YOUR QUESTIONS,

RIGHT QUESTIONS IS LIKE THAT:-

THE SIDE OF AN EQUATION TRIANGLE MESAURE 9√3 ,FIND IT'S AREA?


given that:-

side =9√3
we know that:-

area of equilalateral triangle=
$\frac{ \sqrt{3} }{4} \times {(side)}^{2} \\ \\ \frac{ \sqrt{3} }{4} \times {(9 \sqrt{3}) }^{2} \\ \\ \frac{ \sqrt{3} }{4} \times 81 \times 3 \\ \\ \frac{243 \sqrt{3} }{4} \\ \\ \frac{243 \times 1.73}{4} = \frac{420.39}{4} = 105.0975 {unit}^{2}$
I HOPE ITS HELP YOU DEAR,. THANKS
