![y=x^(2)](https://img.qammunity.org/2019/formulas/mathematics/college/16ajpekpk3cb3e8vbtxbxh080ds0uap5km.png)
Explanation:
the area of a rectangle is determined by the product of its sides, now, if its sides are equal this figure has the name of square and its area is
Area= side1 * side2
a square has both sides equal
Area =side*side
![A=side^(2)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/v1h7nv433b6opjup9ogj0yhwld2bd2wdi6.png)
if we take it to terms of function
we have
![y=x^(2)](https://img.qammunity.org/2019/formulas/mathematics/college/16ajpekpk3cb3e8vbtxbxh080ds0uap5km.png)
where, x is the side of the square and y is its area.
Have a great day.
