Applying the midsegment theorem, the perimeter of triangle JKL is: D. 19.
The perimeter of triangle JKL = JK + JL + KL
Find the lengths of JK, JL, and KL using the triangle midsegment theorem.
JK = 2(3.5) = 7 units
JL = 2(4) = 8 units
KL = 2(2) = 4 units.
Perimeter of triangle JKL = 7 + 8 + 4
Perimeter of triangle JKL = 19 units.
