To find the area of the arena, you will need to find the areas of the rectangular spaces and the 2 semicircles. Because the formulas are given, I will just substitute in the values and show the work for finding the areas.

To find the perimeter, you will look at the distances of lines that take you around the space. Because two of these spaces are half circles, you will need to find the circumference of the full circle.

Also, the answers need to be given in meters, so all units given in centimeters will be divided by 100 to convert them to meters.

Perimeter:

C= 3.14 x 20 m
C = 62.8 meters

62.8 + 8 + 25 + 8 + 5 + 8 + 10 + 8 + 40= 174.8 meters for the Perimeter

Area:
A = 25 x 8
A = 200 square meters

A = 10 x 8
A = 80 square meters

A = 20 x 40
A = 800 square meters

A = 3.14 x 10^2
A = 314 square meters

Total Area: 314 + 800 + 80 + 200= 1394 square meters

GuDViN [60]

Answer:

Mari needs 27 and 39 oranges for 9 and 13 bags respectively.

Step-by-step explanation:

Consider the below figure attached with this question.

From the below table it is clear the she need 9 oranges for 3 bags.

Number of oranges in each bag = 9/3 = 3 oranges

She packs 3 oranges in each bag.

For 9 bags, the number of oranges = 9×3 = 27 oranges.

For 13 bags, the number of oranges = 13×3 = 39 oranges.

Therefore, Mari needs 27 and 39 oranges for 9 and 13 bags respectively.

Compare the fraction 1:24,000 to the fraction 1:3,168,000; which is the largest rational number
gulaghasi [49]

Answer:

\frac{1}{24,000}

Step-by-step explanation:

we know that

When we compare positive fractions with the same numerator, the largest rational number will be the fraction with the lowest denominator

In this problem we have

\frac{1}{24,000}  and   \frac{1}{3,168,000}

Both numerator are equal

Compare the denominators

24,000 < 3,168,000

therefore

\frac{1}{24,000}  is the largest rational number
