On the drawing of 1:20000 scale, the width of a playground is 2 cm and the length is 3 cm. How many square meters is the actual area of the playground?

2 △ 120000 = 40000 (CM) = 400 (m), 3 △ 120000 = 60000 (CM) = 600 (m), 400 × 600 = 240000 (M2); a: the actual area of the playground is 240000 m2

Draw a rectangular piece of land on the paper with a scale of 1:200. The perimeter is 18 cm and the ratio of length to width is 5:4. How many square meters is the actual area of the land?

Suppose the width of a rectangle is x cm, then the length is 54x cm, and because the length + width = 18 △ 2 = 9 (CM), that is, x + 54x = 9, & nbsp; & nbsp; & nbsp; 94x = 9, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 4; length: 9-4 = 5 (CM); actual length: 5 ／ 1200 = 1000 (CM) = 10 (m); actual width: 4 ／ 1200 = 800 (CM) = 8 (m); actual area of this land: 10 × 8 = 80 (M2); answer: actual area of this land is 80 square meters

There is a rectangular test field 200 meters long and 100 meters wide. We need to draw it on a 1:2000 scale drawing. What is the area on the drawing?

200m = 20000 cm, 100m = 10000 cm, 20000 × 12000 = 10 (CM), 10000 × 12000 = 5 (CM), 10 × 5 = 50 (square cm); a: the area on the map is 50 square cm

Sunshine Garden Primary School has a rectangular playground, 350 meters long and 200 meters wide. It is drawn on a 1:10000 scale plan. How much is the length and width?
Please draw a plan of the playground

Distance on the map = actual distance × scale
The actual length is 350 × 1 / 10000 = 0.035m = 3.5cm
The actual width is: 200 × 1 / 10000 = 0.02M = 2cm
This platform, unable to draw, please understand
If you don't understand, please ask

Draw a rectangle 100m long and 80m wide on a drawing at the scale of 1:10000. What is the length and width of the rectangle on the drawing?
[equation (⊙ o ⊙]

Let the length on the graph be x cm
100 m = 10000 cm
x：10000＝1：10000
10000x＝10000×1
10000x＝10000
x＝10000÷10000
x＝1
Let the width on the graph be y cm
80 m = 8000 cm
y：8000＝1：10000
10000y＝8000×1
10000y＝8000
y＝8000÷10000
y＝0.8

A rectangular public square is 120 meters long and 70 meters wide. How many centimeters are it in length and width when it is drawn on a 1 / 2000 scale drawing

12000 / 2000 = 6cm
7000 / 2000 = 3.5cm

(1) On a map with a scale of 1:2500000, the distance between Tianjin and Beijing is 4.8 cm. How many kilometers is the actual distance between Tianjin and Beijing?

The actual distance from Tianjin to Beijing is xcm
1/2500000＝4.8/ x
x＝4.8×2500000
x＝12000000
12000000cm＝120km
A: about 120 km

On a map with a scale of 1:6000000, the distance between Tianjin and Beijing is 1.8cm, and on a map with a scale of 1:500000,
What is the distance between Tianjin and Beijing?
Equation formula

If you are sure you have the right number, it is the distance from Tianjin to Beijing, which is 21.6cm

The actual distance between Beijing and Tianjin is 120 km. The distance between the two places measured on a map is 8 cm. Find the scale of this map

1：15000000

The distance between Tianjin and Beijing is 4.8 cm measured on a map with a scale of 1:2500000. How many kilometers is the actual distance between Tianjin and Beijing?
Two methods are used

981250464ww,
The first one is the first one
4.8 cm = 0.000048 km
0.000048 △ 1 / 2500000 = 120 (km)
Second:
4.8 × 2500000 = 12000000 (CM) = 120 (km)

On the drawing of 1:20000 scale, the width of a playground is 2 cm and the length is 3 cm. How many square meters is the actual area of the playground?
