Hello
All square numbers ends with 0,1,4,5,6 or 9 at units place.
<span>Let makes the table neater. event D= 100m, even E=800m
(Event D) (Event E)
A won the race (Event A) 30 50
B won the race (Event B) 60 25
A and B tied (Event T) 10 25</span>
B did not win the race today. What length of the race was it more likely to have been? The question is asking in what event did the chance of B did not win(lose + ties) is more likely. Then, you need to determine the chance for B did not win <span>in both race.
Chance of B </span>did not win <span>100-m= 30+10/10=40%
</span>Chance of B did not win 800-m= 50+25/10=75%
The difference would be 75%-40%=35% more likely to lose 800-m race
Maybe, 150-100=50 on each triangular side. 50*height(80)=4000 divided by 2=2000. 2000 *'s 2, since we have to count the other side. Now, we have 100 left. so top of rectangle,(48 ft) times what's left of height. 48*(80-64=16) 16=768. Which covers the width of the big column, (48) and leftover height. Next, we find out the 2 left columns, one on each side of rectangle. Find area of rectangle, (what's left) 100. 100*80=800. 800- area of rectangle. Area of rectangle= 3072. Almost lastly, 4000 plus 800= 4800, then, 4800-3072=1728. I believe that the correct answer for the area of the lawn is 1,728 feet.
