The perimeter is the sum of all a shapes sides.
so if length is two times the width, you could write it as 2w.
2w + 2w + w + w = 42. Simplified, it's 6w = 42.
Divide both sides by 6, and you get w = 7.
Since the length is 2w, 2 * 7 = 14, so the length is 14
Area of rectangle is length * width, so do 14 * 7 which is 98. Slap on some units and your answer is 98 sq m
Answer:
the statements given above are true.
Step-by-step explanation:
Given that Frederick designed an experiment in which he spun a spinner 20 times and recorded the results of each spin.
He spun a 4 five times.
The statements true are:
i) For the experimental outcomes to be closer to the predicted outcome, the number of trials should be increased.
iii) If the number of trials is changed, the experimental probability also changes.
iv) If the number of trials is changed, the predicted number of outcomes also changes.
v) If the number of trials is changed, the number of experimental outcomes also changes.
