Experimental probability means what the probability is concluded by the experiment / trials / real results

Assuming {Section 3 I 32} , means it landed there 32 times out of 80.
We write this as a fraction:
32/80 , we simplify it:
16/40
8/20 <- notice how i'm just halving until I can't anymore
4/10
2/5 <- the simplest answer

The answer is D) 2/5

80 square units
Divide the figure into 4 small triangles, 2 rectangles, and one big rectangle on the center.

Area of ONE small triangle:
1/2 • 2 • 2 = 2 square units
Multiply that by 4 because we have 4 small triangles: 2 • 4 = 8 square units

Area of ONE small rectangle:
2 • 6 = 12 square units
Multiply that by 2 bcos we have 2 of those rectangles: 12 • 2 = 24 square units

Area of the big rectangle on the center:
6 • 8 = 48 square units

ADD the area of the big rectangle, 4 small triangles, and 2 small rectangles:
48 + 24 + 8 = 80

FINAL ANSWER: 80 square units
