Use the distance formula!
d = square root of (x2-x1)^2 + (y2-y1)^2

Answer:
Length = 13 cm
Step-by-step explanation:
Length (L) = 2 x Width (W) + 5
2 x (L + W) = 34
2 x (2W + 5 + W) = 34
6W + 10 = 34
6W = 34-10 = 24
W=4
L = 13
There are 84 because if they have the same amount and when you add 42 it's doubled 42+42=84 84/2=42 so she will end up with 84
