The area of Helen's shop is 4800 meters squared because 60 times 80 is equaled to 4800.
If the parking lot is two times long as it is wide and has a width of 50 meters, we should know that if we multiply 50 times two we should get the length of the parking lot which is 100 meters.
We then need to multiply 100 times 50 to find the area of the parking lot. 100 times 50 equals 5000. So, the area of the parking lot is 5000 meters squared.
To find the total of the store's area plus that parking lots area, add the area we got for the store to the area we got for the parking lot. When you add 4800 plus 5000 you should get 9800 meters.
So, the sum of the area of Helen's shop and the parking lot is 9800 meters squared.
