What is the area of a hexagon with a side length of 10? it also has a rectangle in it with other measurements but the question i
Anastaziya [24]

Answer:

there is a formula for a hexagon ..  it's

Area = 3\sqrt{3\\}/2 * length^{2}

where length is the length of one side, assuming all sides are equal

Step-by-step explanation:

3*\sqrt{3}/2= 7.348469228.........

since the length is 10...   the length squared is 100

then the total area of the hexagon is 734.8469228...... units^{2}.. what ever they are

if you want to work with some concepts.. you could also say that a hexagon is just a box with the corners cut off and the triangles that are missing are the equilateral right triangles with a hypotenuse of 10 .  and since 2 pieces of those triangles make a square.. you can subtract two squares of that size from the bigger box that the hexagon fits into.  this is a long way to figure this out but might be good for trigonometry practice   :)

it will also be 734.8463288.....  see if you can work that out :)

Vikentia [17]

Answer:

86

Step-by-step explanation:

let the numbers be x,x+2,x+4,x+6

Then x+x+2+x+4+x+6=332

4x=332-12=320

x=320/4=80
