, so that

. Then the ODE is




This is separable, so you have

Integrate both sides, solving for

if possible, then replace using

and solve for

if possible.
It is an outcome, due to the probability of it happening.

Answer: a) P=10c b) A=4(c^2)
Step-by-step explanation:
the length of each side is c
a) the perimeter is the border of the whole shape. we can see here there are 4 squares but together. each square has 4 sides however since they are connected, we only count 10 of them for the perimeter. 4 for the top and bottom and 1 on each side (4+4+1+1)=10. so it would be 10c
b) area is width x length. which is c x c or c^2. multiply this by however many squares there are. in this case its 4. so it would be 4 x (c^2) or 4(c^2)
