What is the area of the regular polygon?
BartSMP [9]

Answer:

You could use the polygon area formula OR here's an easier solution

We draw the lines DC and DE

Angle ADC = 120°

Triangle ADC is a 30 60 90 triangle

In such a triangle Line AE = hypotenuse * sq root (3) /2

Line AE = 3 * 0.8660254038  = 2.5980762114

Line DE = 1.5

Area of Triangle ADE = .5 * 1.5 * 2.5980762114 =

1.9485571586   square meters and entire area of Triangle

ABC = 6 * 1.9485571586

which equals 11.6913429513  square meters

a {}^{2} +  b {}^{2} =  c {}^{2}
Add the numbers in
{30}^{2}  +  {b}^{2}  =  {50}^{2}
start simplifying
{b}^{2}  = 1600
b = 40

So, the leg has a length of 40 mm.
