Finding Area on a Coordinate Plane — Quiz

Question 6 • Algebra I

Which rectangle has an area of 40 square units?

Answer
A
Image with description On a coordinate plane, the x axis ranges from negative 4 to 4 and y axis ranges from negative 5 to 3. A rectangle is drawn that has vertices at (negative 4 comma 1), (4 comma 1), (4 comma negative 4), (negative 4 comma negative 4).
B
Image with description On a coordinate plane, the x axis ranges from negative 4 to 4 and y axis ranges from negative 5 to 3. A rectangle is drawn that has vertices at (negative 4 comma 1), (4 comma 1), (4 comma negative 3), (negative 4 comma negative 3).
C
Image with description On a coordinate plane, the x axis ranges from negative 4 to 4 and y axis ranges from negative 5 to 3. A rectangle is drawn that has vertices at (negative 4 comma 1), (4 comma 1), (4 comma negative 5), (negative 4 comma negative 5)..
D
Image with description On a coordinate plane, the x axis ranges from negative 4 to 4 and y axis ranges from negative 5 to 3. A rectangle is drawn that has vertices at (negative 4 comma 1), (3 comma 1), (3 comma negative 4), (negative 4 comma negative 4).

Explanation

For choice A, the rectangle extends from x = −4 to x = 4, so its width is 8 units. It extends from y = −4 to y = 1, so its height is 5 units. The area is 8 × 5 = 40 square units, so the rectangle in choice A has the requested area.
