Question

what is the formula of square​

Answer 1

Side * side
Simple and easy

Answer 2

side*side

To better our understanding of the concept, let us take a look at the derivation of the area of a square. Let us consider a square where the lengths of its side are ‘a’ units and diagonal is ‘d’ units respectively. As you all know that area of a square is the region which is enclosed within its boundary. As we have already mentioned, that a square is a special case of a rectangle that has its two adjacent sides being of equal length. Therefore, the area can be expressed as –

Area of a rectangle = Length × Breadth

Area of square = Length x Breadth

Area of square = a× a = = a²
