Is the perimeter of the two figures the same in the following questions? Why

Is the perimeter of the two figures the same in the following questions? Why

If you draw a wavy line in the middle of a rectangle or square, the perimeter is exactly the same, but the area is not the same

The rate of advance between two adjacent length units is 10, and that between two adjacent area units is 100______ (judge right or wrong)

For example, the rate of advance between kilometer and meter is 1000, and that between hectare and square meter is 10000. Therefore, the statement that "the rate of advance between two adjacent length units is 10, and that between two adjacent area units is 100" is wrong

The school is going to rebuild the playground with a circumference of 220 meters. If the reconstructed playground has the largest area, how much should it be?
rectangle

Analysis: known circumference 220 meters, because the square area is the largest, so 220 △ 4 = 55 meters, 55 × 55 = 3025 square meters, but the problem added that it needs to be rectangular, then you can subtract 1 meter and add 1 meter when the side length is 55 meters, that is 54 meters and

If you know the circumference, how to calculate the area of a circle
The circumference of a circle is 6.28

What is the radius of the circle
6.28÷3.14÷2＝1
What is the area of a circle
1×1×3.14＝3.14

How to calculate the area and perimeter of a circle

Area of circle = 3.14 × radius × radius
Circumference of circle = 3.14 × diameter = 3.14 × radius × 2

What are the area and perimeter of a circle?

How to calculate the perimeter and area of the bottom of sixth grade mathematics? Help me!
I am sick during this class, I don't understand! I hope you can help me!

Base circumference = the sum of base length plus base width multiplied by 2
Bottom area = the length of the bottom multiplied by the width of the bottom

The circumference of a semicircle is 8.28 decimeters. Find the area of the semicircle

2 × R + 3.14 × 2 × R △ 2 = 8.28; r = 1.61 decimeters; area = 3.14 × 1.61 × 1.61 △ 2 = 4.069597 square decimeters. Hello, I'm very happy to answer your questions.

How to calculate the area and perimeter of a semicircle? How to calculate the perimeter and area of a circle?

Half area = 3.14 times radius times radius divided by 2
Half face circumference = 3.14 times diameter divided by 2 + diameter
Total area = 3.14 times radius times radius
Perimeter = 3.14 times diameter
