200!!!! because it’s 5x20 in each triangle and you divide by 2 so 5x20 is 100 and 100 divided by 2 is 50 and there are 4 squares so 50 x 4 and you get 200 hope that helped!!
Answer:
Modification has not reduced the number of accidents.
Step-by-step explanation:

A B C D E F G H
Before modification 5 7 6 4 8 9 8 10
After modification 3 7 7 0 4 6 8 2
Difference -2 0 1 -4 -4 -3 0 -8
Mean of differences 
Standard deviation of differences = 
Formula of paired t test :

Df = n-1 = 8-1 =7

t critical> t calculated
So, We failed to reject null hypothesis
Hence modification has not reduced the number of accidents.
50 because half of the numbers in 100 are even and all even numbers are divisible by two
