For the first day, she dug eighteen twentieth of a meter =
x 1 meter

meters
The second day, she dug nine twentieth of a mater =
x 1 meter

meters
Total length of the trench =
+ ![\frac{9}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B20%7D)
= ![\frac{18 + 9}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B18%20%2B%209%7D%7B20%7D)
= ![\frac{27}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B27%7D%7B20%7D)
= 1![\frac{7}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B20%7D)
= 1.35 meters
Total length of the trench is 1.35 meters.
A reasonable estimate of the total length of the trench is 1.00 meter.
