Question

For trapezoid JKLM, A and B are midpoints of the legs. Find AB.

Question 16 options:

A) 29

B) 20

C) 59

D) 58

Answer 1

29

Explanation:

The length of the median of a trapezoid equals one-half the sum of the lengths of the bases.

`\begin{array}{rcl}AB & = & (1)/(2)(JK + LM)\\\\& = & (1)/(2)(19 + 39)\\\\& = & (1)/(2)* 58\\\\& = & \mathbf{29}\\\end{array}`
