What is the perimeter of the trapezoid graphed below?

The perimeter is the sum of the lengths of the sides.

1) Upper base: 6 - 4 = 2 units

2) Lower base: 8 - 2 = 6 units

3) left side:

left side ^2 = (4 - 2)^2 + (9 - 4)^2 = 2^2 + 5^2 = 4 + 25 = 29

=> left side = √29 units

4) rigth side = (8 - 6)^2 + (9 - 4)^2 = 29

=> right side = √29 units

5) Perimeter = 2 units + 6 units + √29 units + √29 units = 8 + 2√29 units

option D. 8 + 2√29 units

Is 8.50 an answer or no? ?
