Answer:
.
Explanation:
Let
be the length of the base.
The question states that the length of each congruent side is
less than twice the length of the base. Twice the length of the base would
. The length of each congruent side would be
.
Sum up the length of each side to find the perimeter of this triangle:
.
Substitute in the actual perimeter of this triangle:
.
Solve for
:
.
Therefore, the length of the base of this isosceles triangle would be
.
