문제2
Point A of rectangle ABCD is located at (-3, 12) and point C is located at (9,5).What is the area of
rectangle ABCD?
Point A of rectangle ABCD is located at (-3, 12) and point C is located at (9,5).What is the area of
rectangle ABCD?
정답:
84
Explanation/Reference:
If point A is located at (-3,12) and point C is located at (9,5), that means that either point B or point D has
the coordinates (-3,5) and the other has the coordinates (9,12). The difference between the different x
values is 9 - (-3) = 12 and the difference between the different y values is 12 - 5 = 7. The length of the
rectangle is 12 units and the width of the rectangle is seven units. The area of a rectangle is equal to its
length multiplied by its width, so the area of ABCD= (12)(7) = 84 square units.
