The reasonable estimate for the length if she uses 18 beads is 34.2 cm.

Explanation:

The scenario says that Maryanne is making a bracelet using 1.9 cm beads and that she is going to use 18 beads. So, in order to determine the estimate length, you need to multiply the length of each bead for the number of beads that she is going to use:

1.9 cm*18= 34.2 cm
