Help please! I will become a fan! picture attached below!
Maybe this will help ( http://www.efg2.com/Lab/FractalsAndChaos/EquilateralTriangle.gif )
I still don't get it? @Grazes
a=13|dw:1360037610134:dw| Area=base*height
@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?
still a little confused.
The length of a equalateral triangle is\[ (x/2)\sqrt{3}\] where x is the length of one side
alright thanks so the answer would be 62.4 cm?
One more question am I correct on the following ?
I have ~124.707658145 for the answer.
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
yeah i got that so the choice closest to what you have on your question (image) is 62.4 cm^2
You're right. My bad. Google's calculator is being stupid.
Alright what about the question I just asked is my answer correct?
alright thank you!
(14.1*9)/(2*12)=5.2 which must round up to 6.
yes, i believe so its 6. :)
