Convert 300% into decimals. So move the decimal point 2 times to the left and you get 3.00 and multiply it by 5 and square it because area of square is s^2
Answer:
The length of line segment AB = 3.4 cm.
Step-by-step explanation:
Given:
The area of the regular octagon is approximately = 54 cm²
A regular octagon has an apothem with length = 4 cm
AB = side of the octagon
To Find:
AB = side of the octagon = ?
Solution:
A regular octagon has an Eight equal Side
We Know that,
substituting the given values in equation we get
Now,
Perimeter = 8 × Side
∴ Perimeter = 8 × AB
∴ 27 = 8 × AB
∴ 
After rounded to nearest 10th we get
AB =3.4 cm
The length of line segment AB = 3.4 cm.
A statement also know as an axiom which is taken to be true without proof.

Answer:
6√3
Step-by-step explanation:
Let's take the vertical side in the middle as y and the side on the left as z.
We have:
from the right triangle on the right:
9²+y²=x²
from the right triangle over the big triangle:
z²+x²=(9+3)²=12²
from the right triangle on the left:
3²+y²=z²
We can use substitution in our three equations to get x.
9²+y²=x²
z²+x²=12²
3²+y²=z²
First, solve for y² in terms of x². We want everything in terms of x so we can solve for it.
9²+y²=x²
subtract 9² from both sides
x²-81 = y²
plug that into the third equation
3²+(x²-81)=z²
x²-72=z²
z²+x²=144 (the second equation)
plug x²-72 for z²
x²-72+x² = 144
add 72 to both sides
2x² =216
divide both sides by 2 to isolate x²
x²=108
square root both sides to get x
x = √108 = 6√3
