Answer:
here is your answer
Step-by-step explanation:
Let breath be b and length be L
given condition
b=5 - L. (1A)
and b+2+L+2=25cm^2 (1B)
substitute (1A) in (1B)
So,5 - L +2+L+2=25cm^2
L gets canceled
So, 25cm^2 is 25000
therefore, 25000/5-2-2
5000/-2-2
-2500/-2
1250
L=1250
b=5-L = 5 - 1250= -1245
