Draw a rectangular piece of land with the ratio of length to width of 5:3 on the map with the scale of 1:500. What is the length of the land It's urgent!

There are few conditions for this problem

Draw a rectangle with a length to width ratio of 5:3 on the drawing with a scale of 1:500. The length of the rectangle is 5cm. What is the actual length and width?

5*500=2500
3*500=1500

Draw a picture on a rectangular land with a scale of 1:200. The perimeter of the rectangle is 64cm and the ratio of length to width is 5:3. Calculate the actual area

64 / 2 = 32 cm
Length: 32 / (5 + 3) * 5 = 20cm
Width: 32-20 = 12cm
Actual length: 20 * 200 = 4000 cm = 40 m
Actual width: 12 * 200 = 2400cm = 24m
Actual area: 40 * 24 = 960 square meters

The perimeter of the rectangle is 110cm, the width increases by 25%, the length decreases, and the perimeter remains unchanged
The perimeter of the rectangle is 110cm, the width increases by 25%, the length decreases by 1 / 7, and the perimeter remains unchanged.

Let the length of the original rectangle be a (CM), and the width be B (CM). In the original rectangle, there is 2A + 2B = 110, that is, a + B = 55
