China's territory is about 5000 kilometers long from east to west and 5500 kilometers from north to south, on a scale of 1:8000000

China's territory is about 5000 kilometers long from east to west and 5500 kilometers from north to south, on a scale of 1:8000000

500000000 ／ 8000000 = 500 ／ 8 = 62.5cm -- east west length
550 million ÷ 8000000 = 550 ／ 8 = 68.75cm - North South length

On a map with a scale of 1:1000, the foundation of a house is 8 cm long and 5 cm wide. What is the area of this house?

8÷1
one thousand
=8×1000
=8000 (CM)
=80 (m);
5÷1
one thousand
=5×1000
=5000 (CM)
=(50 m);
80 × 50 = 4000 (square meter)
A: the area of this house is 4000 square meters

The base and height of a parallelogram measured on a 1:300 map is 8 cm 5 cm. What is the actual area

8x5x300 = 12000 square centimeter

Find a map of China and estimate its area?

China's official land area is about 9.6 million square kilometers
You're not a math problem. You're a brain teaser

The scale of a picture is 1:5000. The radius of a circular pool measured on this map is 0.5cm, and the floor area of this pool is______ Square meters

The radius of the pool is:
0.5÷1
5000 = 2500 (CM) = 25 (m),
area covered:
3.14×252，
=3.14×625，
=1962.5 (M2);
So the answer is: 1962.5

On a map with a scale of 1:5000, the area of a lake on the map is 12 square centimeters. Find out the actual area of the lake It seems that 5000 of them should be squared

30000 square meters

On a map with a scale of 1:5000, the perimeter of a polygon is 72cm and the area is 32cm05 The actual perimeter and area of the zone

Perimeter = 72 * 5000 = 360000cm = 3.6km
Area = 32 * 5000 * 5000 = 80000m2 = 0.08km2

A rectangular vegetable field 80 meters long and 60 meters wide is drawn on a 1:2000 scale map. What is the area on the map

(80/2000)*(60/2000)=0.0012m^2

On the scale of 1:5000, there is a rectangular land of 3.2 cm and 1.2 cm wide. What is the actual perimeter and area of this land?

3.2 × 5000 = 16000cm = 160m
1.2 × 5000 = 6000 cm = 60m
(160 + 60) × 2 = 440m perimeter
160 × 60 = 9600 square meters

The scale of the plan of a rectangular vegetable field is 1:500. What is the ratio of the area on this vegetable map to the actual area

It's 1:250000
