Answer:
L=6 cm l=3
Step-by-step explanation:
x+y=45
L=2l
Big Square Area
L*L=x
Little Square
l*l=y
Substituting
(L*L)+(l*l)=45
(2l*2l)+(l*l)=45
(4l^2)+(l^2)=45
5l^2=45
l^2=45/5
l^2=9
l=sqrt(9)
l=3
L=2(3)
L=6
The are is A=W*L
The perimeter is P=2L+2W
So there is some form of relationship.
A/W=L and P-2W=2L
A/W=L and (P-2W)/2=L
A/W=(P-2W)/2
2A/W=P-2W
2A=PW-2W^2
If you line them up according to the quadratic formula you can have
2W^2-PW+2A=0 where W is the variable equivalent to X in normal circumstances and P and A are set values. There is always a relationship between two numbers, or at least you can almost always create your own relationship. This may seem rather complicated but this is a complicated question and I applaud you for asking something of this sort.
