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
