The correct answer is D!! Please choose me brainliest!!! Thank You!!!
Step-by-step explanation:
Based on the given condition, since the rectangle is inscribed in a circle given the length to be 3x, the width can be approximated by taking the right triangle formed by the radius and the w/2, sin 45 = w/2/r, which is equal to w = 2r sin45, therefore the Area of the inscribed rectangle = LxW = (3x)(2rsin45)
An equation of circle has form

So, the center is (13;1)
Now we need to find a radius
Let's create an equation

So radius is 2
50 is not a perfect square because it does not have a perfect square root where as 49 is 7, 121 is 11, and 1 is 1
