Question

PLZZZZZZZ HELP IM BEING TIMED!!!!!!!!!!!

Trapezoid ABCD has the following measurements, where AB is parallel to DC. AB = 19 mm, AD = 30 mm, DC = 34 mm, BC = 20 mm
What is the length of the median of the trapezoid?
A. 51.5 mm
B. 106 mm
C. 25 mm
D. 26.5 mm

Answer 1

D. 26.5 mm

Explanation:

A median of trapezoid is a line segment between the midpoints of the legs of a trapezoid (look at the picture).

The formula of a length of a median of a trapezoid:

`(a+b)/(2)`

a, b - bases

We have a = AB = 19mm, and b = DC = 34 mm. Substitute:

`(19+34)/(2)=(53)/(2)=26.5\ mm`
