 Hi, and welcome to the session. Today, we will discuss the following question. The question says, explain why a rectangle is a convex quadrature. Let's see its solution. Let's see a figure of a rectangle. Alright, here we have a rectangle a, b, c, d. Now, here a, c and b, d are the diagonals of this rectangle. Now, let's recall the definition of a convex polygon. Now, polygons that are convex have no portions of their diagonals in their exterior. Here, a, c, b, d are the diagonals of the rectangle a, b, c, d. As we can see that a, c and b, d both lie in the interior of the rectangle. So, what can we say? The rectangle a, b, c, d satisfies the property of convex polygons. Hence, a rectangle is a convex quadrature because both of its diagonals lie in its interior. This is our final answer for this question and with this, we finish the session. Hope you must have understood the question. Goodbye, take care and have a nice day.
