Question
A rectangle $M N P Q$ has three of its vertices at $M(0,0)$ $N(a, 0),$ and $Q(0, b) .$ Find the fourth vertex $P$ and the area of the rectangle $M N P Q$.
Step 1
This is because in a rectangle, opposite sides are equal. Therefore, the x-coordinate of $P$ is the same as $N$ and the y-coordinate of $P$ is the same as $Q$. So, the coordinates of $P$ are $(a, b)$. Show more…
