A rectangle on the coordinate plane has opposite vertices at (−2, 1) and (5, 6), with sides parallel to the axes. What is its area?
Show hints
- Find the coordinate difference on each axis.
- Multiply 5 − (−2) by 6 − 1.
Show the answer and solution
Answer: 35
The horizontal length is 5 − (−2) = 7, and the height is 6 − 1 = 5. The area is 7 × 5 = 35.
