An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result,
the altitude cuts the base into two equal segments. The length
of the altitude is 5 inches, and the length of the base is 2 inches.
Find the triangle's perimeter. Round to the nearest tenth of an
inch.
