The length of a side of square is 5.
Step-by-step explanation:
Given,
Area of square = a²
Perimeter of square = 4a
According to given statement;
Area of square = Perimeter + 5
Factorizing the equation;
Either,
a-5=0 => a=5
Or,
a+1=0 => a= -1
As length of a side cannot be negative, therefore,
Length of a side of square = 5
The length of a side of square is 5.
