Answer: P=30 Yards
Step-by-step explanation:
Okay, so they want to double the AREA of the parking lot. So first you want to find the area of the original parking lot.
So, 10*20-20=180 Yards.
Now, we know that the area of the original parking lot is 180 yards and they are doubling the area of the parking lot.
Since they are doubling it, we know that the expansion is the same size as the original. So, the area of the expansion is also 180 Yards.
In order to find side P we must find one of the other sides. The side of the expansion that is all the way to the right is 6 yards, because 10-4=6 yards.
So now we do the area of the expansion divided by 6 to get side P.
180/6=30
P=30 Yards
