The area of a square is :
4p%5E2-4p%2B1sq.in.
Find the length of the side of the square.
The area of a square is given by:
A+=+s%5E2 where s is the length of the side of the square.
In this problem, you are given:
A+=+4p%5E2-4p%2B1 so...
s%5E2+=+4p%5E2-4p%2B1 Factor the trinomial.
s%5E2+=+%282p-1%29%282p-1%29 or %282p-1%29%5E2 Take the square root of both sides.
s+=+2p-1in. This is the length of the side of the square!
