The given polygon is a square which means its all sides will be equal.

According to the above statement:-


\tt \: x ^(2) + x = x ^(2) + 4

Let's solve it ~


\tt \cancel{x ^(2) } + x = \cancel{x ^(2) } + 4


\tt \: x = 4


\rule{300pt}{3pt}


\huge{|\underline{\mathtt{\red{S}\blue{i}\orange{d}\pink{e}\blue{s}\purple{:}\green{-}\red{}\blue{}\orange{}}}}


\sf \: x ^(2) + x \\ \sf \: 4 ^(2) + 4 \\ \sf \: 16 + 4 \\ \sf \: 20

Thus, The sides of the polygon will be 20cm each!

Answer:


\huge\boxed{\sf x = 4}

Explanation:

If the given polygon is a regular polygon, its sides are equal.

This means:


x^2+4=x^2+x

Subtract
x^2 to both sides

4 = x

OR

x = 4


\rule[225]{225}{2}

Hope this helped!
