A rectangle is inscribed in a semi circle of radius 2, let x represent half the length of the rectangle. Write an expression for the area of the rectangle in terms of x.
Well I know area=length X width. That's about all I know what to do though

r ^ 2 = x ^ 2 + w ^ 2
2 ^ 2 = x ^ 2 + w ^ 2
4 = x ^ 2 + w ^ 2
w ^ 2 = x ^ 2 - 4
w = sqrt ( x ^ 2 - 4 ) =
A = 2 x * w
A = 2 x * sqrt ( x ^ 2 - 4 )
2 ^ 2 = x ^ 2 + w ^ 2
4 = x ^ 2 + w ^ 2
w ^ 2 = x ^ 2 - 4
w = sqrt ( x ^ 2 - 4 ) =
A = 2 x * w
A = 2 x * sqrt ( x ^ 2 - 4 )

OH! Okay thanks! I was doing something similar, but I guess I was just confusing myself. That was actually pretty simple.
