Help plz don't get this
loris [4]
(I see that your concentrating on the task at hand with those YT and fortnite tabs open)

The area of the parallelogram is "base times height," so its 20*8 which is 160.

To find the area of the triangle, we have to find the base which incorporates Pythagorean'd theorem.
100 - 64 = 36, sqrt 36 is 6. So the base of the triangle is 6, the height is 12.6, thus the area is 6.3 * 6, which is 37.8

Adding the two values up, we get 37.8 + 160 = 197.8
