The banner is around 10.6 feet. It's because all you need to do is to divide 8 by 3, and then add it with 8 times 1 (since it's 1 1/3 times the width of 8 feet). Once you add up the two answers that we first got, you will be able to get 10.66666, or just simply 10.6 feet.
The correct answer is diagonals are equal and bisect each other.
Step-by-step explanation:
A rectangle is a quadrilateral with opposites sides equal in length and all interior angles equal to 90°. Opposite sides are parallel and adjacent sides are perpendicular. Diagonals in a rectangle are equal in length and they bisect each other. If we want to draw a circumcircle, then the point of intersection of these diagonals give the circumcenter.
