Answer:
9.7 , 310.4
Step-by-step explanation:
length of each side = 64/8=8
using theorem Pythagoras
A²=10.5² – (8/2)²
A=9.7 ft
area of triangle
1/2×8×9.7=38.8
area of octagon
38.8×8=310.4
Answer:

The value of the missing length is 20
Let the missing length be x
From Parallel lines and transversal theorem, we have that
If three or more parallel lines intersect two transversals, then they cut off the transversals proportionally.
Then, we can write that
∴
x = 20
Hence, the value of the missing length is 20
