Answer:
Perimeter of a square = 4a inches
Step-by-step explanation:
Explanation:-
Given that the length of a side = a inches
The area of square = a² square inches
we know that square of all sides are equal
Perimeter of a square = a + a + a + a
= 4×a inches
Example:-
Let the length of a square = 4 inches
The perimeter of a square = 4 a
The perimeter of a square = 4 × 4 = 16 inches
