Answer:
792 m
Step-by-step explanation:
perimeter of a rectangle = 2l + 2b
⇒ perimeter of ground = (2 x 42) + (2 x 24) = 132 m
Perimeter = 1 round
⇒ 6 rounds = 6 x 132 = 792 m
Using the probability (conditional) formula, where P is equals to the number of favorable outcomes over the total number of outcomes. Calculating using five and the thirty percent, 1.5 is the answer. But that cannot be the answer.
So we look for the probability using this formula derived from the original, (total outcomes) x (percentage) = (favorable outcomes), 5x=2. That gives us the answer of 0.4 or 40%.
