A rectangle is 20 centimeters long, the length is equivalent to 5 2 of the width, what is its area i

According to the meaning of the problem, according to the area formula column formula calculation 20 (20 2 5) solution idea: the key words in the application problem are average, generally use division, use multiples generally use multiplication, more than who or who is less generally use addition and subtraction, according to the key words to apply columnar formula. Problem solving process:

A: Its area is 160 square centimeters.

Extended Information Vertical Calculation - Calculation Process: Perform a divisor operation on each digit from the high position of the dividend, the quotient obtained from each calculation is retained, and the remainder is added to the next digit for operation, and the number of digits from the dividend will be calculated in this order, and the obtained quotient will be combined in order, and the remainder is the result of the last operation.

Problem solving process: Step 1: 40 5=8 The remainder is: 0 According to the above calculation steps, the combination result quotient is 8, the remainder is 0, please ask if you are in doubt, and you are satisfied.

The area should be: 20*(20*2 5)=160 square centimeters, which is the answer, I hope it will be useful to you.

The length is equivalent to five-fifths of the width, and is equivalent: the width is five-fifths of the length, that is: the length is two-fifths of the width, i.e., the length is two-fifths of the width, so the width is 20 two-fifths of the width 8, so the area is: 20 8 160 square centimeters.

The length is times the width, so the width is 8 centimeters, and the area is 160 square centimeters.

Let's start with the width: 20 5 2 = 8 (cm);

Area: 20 8 160 (cm²).

300 (square divided, jujube, Xunmi, Mengshen).

Answer: The area of this rectangle is 300 square decimeters

Summary. Calculation process: set the width to x centimeters from the meaning of the topic, 20 x = 5 4 so 5x = 80x = 16 so area = length and width = 20 16 = 320 square centimeters.

A rectangle is 20 centimeters long, its length and width ratio is 5:4, and the area of this rectangle is how many square centimeters.

Calculation process: Let the width be medium stupid x centimeters from the meaning of the title, 20 x = 5 4 so 5 x = 80x = 16 and the area = length and width = 20 16 = 320 square centimeters.

How do you calculate a column?

You don't need an equation, dear.

No. Calculation process: width: 20 4 5 = 16 cm area = length and width = 16 20 = 328 square centimeters.

Calculation process: width: 20 4 5 = 16 cm area = length and width = 16 20 = 320 square centimeters.

Typos, forgive <>

The area of the rectangle is length multiplied by width, so width 20 5 = 4cm

Rectangle area = length and width.

The width of the rectangle = the area of the length.

4（cm）

2×(2×1/10)

2 = square decimeter).

Square metre. A: The area of this rectangle is square meters.

300 (flat collapse quietly decimeter).

Answer: The area of this rectangular shirt is 300 square decimeters

20x brackets 20-5 brackets equal to 300 square decimeters.

If its width is 1 decimeter, i.e. meter, so the length is 2 meters = 200 decimeters;

If it is 25 cm long, i.e. meters, so the width is 2 meters = 50 cm.

Length: 20 divided by 2 3 = 30 cm.

The area of the rectangle: 30x20 = 600 square centimeters.

20/(2/3)=30cm

Area = length times width = 600 square centimeters.
