Scientists in the jungle want to find the best estimate for the lion population. They tagged (marked) and released 20 lions as part of a research project. Later, they found 160 lions, 8 of which were tagged (marked). Find the best estimate of the total population of lions: Step 1: Set up an equivalent proportion where "X" is the unknown total lion population. Step 2: Cross Multiply and set two equivalent equations. Step 3: Solve for "X" by dividing both sides by the number associated with "X" (Inverse operations) to find the total lion population. Hint: For every 8 tagged lions in the sample, there are 160 lions in the population. How many lions are there in the population if there are 20 marked lions in the sample?

Ответ:
perimeter: 2(2ft * 8ft) =
area: 2ft * 8ft =
just do this, im not sure
Step-by-step explanation:
so you just get the dimensions then put them between brackets (for perimeter); and for area you multiply them by each other
