A square with a side length of 5cm has a circumference of () and an area of ()

A square with a side length of 5cm has a circumference of () and an area of ()

A square with a side length of 5cm has a perimeter of 20cm and an area of 25cm

The side length of a square is 0.9 decimeter, its perimeter is () decimeter, and its area is () square decimeter

The side length of a square is 0.9 decimeters, its perimeter is (3.6) decimeters, and its area is (0.81) square decimeters
Note: square perimeter = side length X4
Square area = side length x side length

If the side length ratio of two squares is 4:1, what is their perimeter ratio______ ：______ And the area ratio is______ ：______ If the edge length ratio of two cubes is 3:1, then their surface area ratio is______ ：______ And the volume ratio is______ ：______ ．

(1) According to the above analysis, we know that the ratio of their perimeter is: (4 × 4): (1 × 4) = 16:4 = 4:1. The ratio of their area is: (4 × 4): (1 ×) = 16:1. A: if the side length ratio of two squares is 4:1, then their perimeter ratio is 4:1 and the area ratio is 16:1

A square with a side length of 4cm has the same perimeter and area______ (judge right or wrong)

The perimeter is 4 × 4 = 16 (CM); the area is 4 × 4 = 16 (cm 2); the value of perimeter and area is the same, but the units are not the same, and the length unit and area unit cannot be compared

The perimeter of a square is 4 / 7 meters. How many meters is its side length and area

Side length is 4 / 7 divided by 4 = 1 / 7 meter
The area is (1 / 7) * (1 / 7) = 1 / 49 square meters

The side length of the square is increased by 1 / 8, the perimeter is increased, and the area is increased by how much

Perimeter increased by 1 / 2
Area increased by 17 / 64

The ratio of the circumference of a rectangle to that of a square is 6:5. The length of a rectangle is 1 and two fifths of its width. Find the ratio of the area of the rectangle to that of the square
Don't try to solve the linear equation of two variables
The perimeter ratio of a rectangle to a square is 6: the length of a rectangle is 1 and two fifths of its width. Find the area ratio of the rectangle to the square

Let the rectangle be 7 / 5 x in width x and 2 (x + 7 / 5 x) = 24 / 5 x in circumference
If the square is 4x, it becomes x, so the area ratio is (X.7 / 5x) / (x.x) = 7 / 5

The perimeter ratio of a rectangle to a square is 5:4, the length to width ratio of a rectangle is 3:2, and what is the area ratio of a rectangle to a square?

Because the ratio of the length and width of a rectangle is 3:2, the length and width of the rectangle can be regarded as 3 parts and 2 parts, and the perimeter of the rectangle is 3 + 3 + 2 + 2 = 10. Since the ratio of the perimeter of the rectangle to the perimeter of the square is 5:4, 10 divided by 5 and multiplied by 4 can get the perimeter of the square as 8, then the side length is 8 divided by 4 = 2
Area of rectangle = 3 times 2 = 6
The area of a square is 2 times 2 = 4
So the area ratio of rectangle and square is 6:4 = 3:2

The perimeter ratio of a rectangle to a square is 5:4, the length to width ratio of a rectangle is 3:2. The area ratio of a rectangle to a square is 5:4______ ．

Let the perimeter of the square be 8, then the perimeter of the rectangle is 10, so the side length of the square is 2, the length and width of the rectangle are 3 and 2 respectively, the area of the rectangle: 3 × 2 = 6, the area of the square: 2 × 2 = 4, the area of the rectangle: the area of the square = 6:4 = 3:2; so the answer is: 3:2

The ratio of the circumference of a rectangle to that of a square is 6:5, and the length of a rectangle is one and two-thirds of its width. Find the ratio of the area of the rectangle to that of the square. Use the ratio instead of the equation. Thank you

6 ／ 2 ／ (1 + 1 and 2 / 5)
=3÷12/5
=5/4
