I'm going to split this shape into 3, 2 triangles and a rectangle. To find the area of the rectangle, you would do 30 × 6 = 180ft. The triangle on the left would be 20 (26 - 6) × 20/2, so 400/2 = 200ft. The bottom triangle would be 6 × 6 (36 - 30)/2 = 36/2 = 18ft. When you add them all up (180 + 18 + 200) you get 398ft as your answer.
(btw i think your on 05.04 mid module check, correct?)
This is just an assumption considering that there are more red than blue but only trumps blue by 2. Taking out those two, you’d be left with a 50% chance of getting red and/or blue marbles
Take away 1,3 it interferes with 1,1 making it not a function. You can use the vertical line test and see if more than one is in a vertical line to find it.
