Let's separate the hexagon into 5 shapes; 2 triangles on each side, and a rectangle in the middle. Now let's find the area of each of the smaller shapes.
Top left triangle:The equation to find the area of a triangle is
(base = b, height = h, a = area)
a = b · h ·

Now let's add in our values and solve.
a = 2 · 4 ·

a = 8 ·

a =
4Now since there are 4 of these triangles, and they're all the same size,
4 · 4 =
16All of the triangles put together =
16cm²The middle rectangle:The equation to find the area of a rectangle is simple:
(w = width, l = length, a = area)
a = w · l
Now let's put in our values and solve.
a = 4 · 8
a =
32The rectangle is
32cm²Now let's add the areas together.
32 + 16 =
48The answer is <span>

Answer:
60
Step-by-step explanation:
since its a square, and has four sides then you would divide total length by four to find the length of each side
Write a system of equations and solve.
x + y = 10
5x + 10y = 90
Multiply and combine equations
-5x - 5y = -50
5x + 10y = 90
------------------
5y = 40
y = 8
x = 2
