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
