Answer:
the side length of square will be =+3
Step-by-step explanation:
perimeter of square=4xa
area of square=a x a=a^2(where a is the side length of the square)
according to the question:
4*a+a^2+4=25
a^2+4a-21=0
a^2+7a-3a-21=0
a(a+7) -3(a+7) =0
(a+7) =0 Or (a-3) =0
since length cannot be negative
a=3
