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

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.
