Question

Find the length of side of an equilateral triangle with area 10.2m^2???

Answer 1

the length is already given ..what do you have to find?

Answer 2

typo, excuse me.

Answer 3

Okay
\[\text{Area of equilateral \triangle }= side^2 \times \frac{\sqrt{3}}{4}\]

Answer 4

Here Area is given and let the side be x
now solve for x

Answer 5

sorry, can we back up for a a minute.

Answer 6

What happened to 1/2 b*h??

Answer 7

1/2 * b* h is the area of a Right triangle (one of the angle is \(90^o\) )

Answer 8

do I need to do something like that?

Answer 9

No ,you don't need a figure to solve this, particular, problem.

Answer 10

Here
Area=10.2 \(m^2\)

Formula:\[\text{Area of equilateral \triangle }= side^2 \times \frac{\sqrt{3}}{4}\]
let the length of the side be \(x\) m

\[\large 10.2 = x^2 \times \frac{\sqrt{3}}{4}\]
