Answer:
0.70710678 is 2 root 1/2 simplified
Step-by-step explanation:
The median is 4
There are 3 numbers below 4. and the lower quartile is the middle number of these 3.
So its 2
A = √1² + 2²
a = √1 + 4
a = √5
a ≈ 2.23
b = 4
c = √3² + 2²
c = √9 + 4
c = √13
c ≈ 3.6
P = a + b + c
P = 2.23 + 4 + 3.6
P = 6.23 + 3.6
P = 9.83
Perimeter of ΔBDE = 9.83 units
