Maybe this will help ( http://www.efg2.com/Lab/FractalsAndChaos/EquilateralTriangle.gif )

I still don't get it? @Grazes

@Foreverisabell Triangle Formula : Area of Triangle = l * b/2 Perimeter of Triangle = a + b + c Area of Equilateral Triangle = (Sqrt(3) / 4) * l² Area of SAS Triangle = ½ * l * b * SinC where l = length, b = breadth a, b, c = sides of triangle

@Foreverisabell Equilateral Triangle Definition: Equilateral triangle is a triangle that has equal length on all three sides.

@some_someone so you would do square root 3 divided by 4 times 12 squared?

8. anonymous

still a little confused.

9. anonymous

The length of a equalateral triangle is$(x/2)\sqrt{3}$ where x is the length of one side

10. anonymous

alright thanks so the answer would be 62.4 cm?

11. anonymous

One more question am I correct on the following ?

12. anonymous

I have ~124.707658145 for the answer.

13. anonymous

Find the area of a equilateral triangle from the given length 3. Find the area. Area = (Sqrt(3) / 4) * l² = (1.73 / 4) * 12² = 0.4325 * 144 = 62.28 so ~ 62.354

14. anonymous

I got 62.345?

15. anonymous

I meant 62.354

16. anonymous

yeah i got that so the choice closest to what you have on your question (image) is 62.4 cm^2

6

20. anonymous

alright thank you!

21. anonymous

(14.1*9)/(2*12)=5.2 which must round up to 6.

22. anonymous

yes, i believe so its 6. :)
