Question

A rectangle on a coordinate plane has vertices at (7, 5), (–7, 5), (–7, –2), and (7, –2). What is the perimeter of the rectangle?

21 units
34 units
42 units
98 units

Answer 1

42 units

Explanation:

From 5 to -2 in the Y-axis, the distance is 7

From 7 to -7 on the X-axis the distance is 14

A rectangle's perimeter = width * 2 + length *2

= 7*2 + 14 *2

= 14 +28

= 42
