Answer:
P = 60, A = 150.
Step-by-step explanation:
One quick way to pick the right choice is to look at the units of measurement. In this case, the units are in feet, so we can presume that option 2 is correct. However, there are other ways to discern this.
20 + 15 + 25 = 60. This is the perimeter of the shape.
The formula for triangle area is (h)(b)/2. Plugging in (12)(25)/2 gives us 150.
Now, if we were to take these measurements and convert into yds., the measurements would be 20 yds to 50 yds sqd.
Therefore, option 2 is correct.
