one side of the wall, parallel to the floor.
From the same corner, an 8-foot long

are the same length as the walls in part
a, and that the 6-foot and 8-foot pieces of
string are extended from the same
corner. Do you think the distance
between the two ends will be the same
as in part b? Explain your reasoning.
