Answer:

The amount of time it takes Shelly to clean each house is 3.6 hours or 2 hours 36 minutes.

Step-by-step explanation:

Shelly cleans 5 different houses in 18 hours.

To compute the amount of times Shelly spends cleaning one house divide the total hours spend by the number of houses cleaned.

The number of hours it takes Shelly to clean a single house is:

I think it is 5 cm squared
In order to find the area of a square, you square the length
If you square the square rot of 5, you get 5
I hope this helps!!
