Question

A rectangular plot of land is represented on a coordinate plane where each unit is one foot. The vertices are at (60,30), (60,90), (100,30), (100,90)?
A. 100 feet
B.200 feet
C. 560
D. 2,400

Answer 1

To find his answer you will find the distance between (60, 30) and (100, 30) (length). How far from 60 to 100. It is 40 feet. The x values are used to see the distance.

To find the height use (60, 30) and (60, 90). How far is it from 30 to 90? These are the y values This is 60 feet.

To find the perimeter add 60+60+40+40. The answer is 200 feet. You can show this as P=200 feet.
