First symmetrically cut the pentagon to get 5 pieces. (So that you will get the idea that this polygon is divided into 5 triangles)
Then find the area of one of the triangles:
Area of Triangle = 
A = 
× 4 × 10
A = 20 m²
To find the area of the whole pentagon shape:
A = 20 × 5 = 100 m²

Answer:
x = 5
Step-by-step explanation:

x = 5
Answer:
1/9
Step-by-step explanation:
Anything to the negative power will be under 1
So take the square and then reciprocate it.
$36.8 because if you do 40 times .08 you get 3.2, after that you do 40-3.2 and you get 3.8. Hope this helps.
