How long does it take to lay a carpet on the stairs that are 3 meters long at the bottom and 2 meters high?

5 meters. There is no need to consider anything very high and deep. The horizontal part is the bottom length (3 meters), and the vertical part is the height (2 meters), so it needs to be paved 5 meters

How many meters of carpet does it take to lay a carpet on a 2-meter-high and 3-meter-long staircase?
Third grade math questions

5m

As shown in the figure, during the exhibition period, a certain Exhibition Center is going to lay carpets on the corridor which is 5m high, 13m long and 2m wide. It is known that the carpet is 18 yuan per square meter. Please help me to calculate. It will cost at least 10 yuan to complete the corridor______ Yuan

According to Pythagorean theorem, AC = AB2 − BC2 = 132 − 52 = 12 (m), then the total length of carpet is 12 + 5 = 17 (m), then the total area of carpet is 17 × 2 = 34 (M2), so it needs at least 34 × 18 = 612 yuan to complete this corridor

A hotel is going to lay a red carpet on the main staircase when it is decorated. It is known that the price of this kind of carpet is 30 yuan per square meter. The width of the main staircase is 2 meters, and its side is shown in the picture
It is known that the length of AB is 5.8 meters, and the length of BC is 3.6 meters?

30×【（5.8+3.6）×2】
=30×【9.4×2】
=30×18.8
=564 yuan

It is measured that the length of the stairs is 5 meters and the height is 3 meters. It is planned to lay carpet on the surface of the stairs. How many meters does the carpet need at least

If you move all the parallel steps down, you will get the bottom edge of the big right triangle
Translate all the vertical steps to the right, which is the side of the big right triangle 3
5²-3²=4²
So the bottom is four meters
3M + 4m = 7M
At least 7 meters
Typing is not easy,

As shown in the figure, carpet is laid on the surface of a staircase with a height of 6 meters, a length of 10 meters and a width of 2.5 meters. If the carpet is 50 yuan per square meter, please help to figure out at least how much it costs to lay the carpet?

According to Pythagorean theorem: ab = ac2-bc2 = 8 (m), х AB + BC = 14 (m), х 14 × 2.5 × 50 = 1750 (yuan). & nbsp; answer: it costs at least 1750 yuan to lay carpet

A rectangular vegetable field is 60 meters wide, equivalent to 3 / 2 of its length. How many square meters is the area?

60 △ 2 / 3 = 90 (m) long
90 * 60 = 5400 (M2) the measure of area

A rectangular piece of land is 60 meters long and 5 / 2 of its length wide. How many square meters is the area of this piece of land

Width is 5:2 of length, so width = 60 × 5:2 = 24,
24 × 60 = 1440 square meters
Han, there's a level 12, idiot?

There is a rectangular vegetable field, which is 60 meters long. The ratio of length to width is 2 / 4. How many meters is the width? 2 how many square meters is the area of this field? 3 in this field, how many square meters are the seed carrying areas of cucumber, watermelon and pepper according to the ratio of 3:2:1?

1.60x2/4=30
2.60x30=1800
3.1800x3/6=900 1800x2/6=600 1800x1/6=300
