W - the width
l - the length
P = 6984
P = 2w + 2l
l = 3w
substitute
2w + 2 · 3w = 6984
2w + 6w = 6984
8w = 6984 |:8
w = 873
l = 3 · 873 = 2619
Answer: the length = 2619 and the width = 873
The population Its 860 u give only 8 points
Well:
100/7= 1/7 probability
1/7 probability (in percent) x 5= 5/7 probability
5/7 probability= 71.4%
The triangle BAC has two known measurements 30 and 90 so add those together and subtract by 180
30 + 90 = 120
180 - 120 = 60°
162 is eighty-one percent of 200
