4, 3, 4,
16, 9, 16
2) Sum the squares of the 2 shortest sides.

Answer:
Time taken by Franklin to shovel alone is 65.5 minutes.
Step-by-step explanation:
Let the time taken by Franklin to shovel alone = x minutes.
Since, the time taken by Angela to shovel = 180 minutes and the time taken by both = 48 minutes.
Then, we have,
Amount of shoveling done in 1 minute by Angela = 
Amount of shoveling done in 1 minute by both = 
Amount of shoveling done in 1 minute by Franklin= 
So, we have,

i.e. 
i.e. 
i.e. 
i.e. 
i.e. x= 65.5 minutes
Thus, the time taken by Franklin to shovel alone is 65.5 minutes.
