Find the area of the parallelogram. HELP ME PLS ASAP PLS PLS PLZ

A.160 ft
B. 160ft^2
C. 240 ft
D. 240ft^2

A. 160 ft

Step-by-step explanation:

If you look at the picture, you can see that you can move the triangle to the other side of the parallelogram. If you do that, you will just see it is just a rectangle. SO it is 8*20 = 160 ft.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
