How many meters does the length of carpet need at least I won't spend the picture

When it comes to the Pythagorean theorem, the ladder has a plane and a vertical face, three meters high and five meters beveled. The other floor is four meters. That is to say, the carpet on the front side should be four meters, and the carpet on the vertical side should be three meters, a total of seven meters. Just draw a picture. If you don't know what the Pythagorean theorem is, use Baidu entry to check

The length of the two wires is 363 meters. If the length of each wire is 3 meters, the second wire is 8 / 9 of the first wire. How long is the first wire?
Such as the title

Let the first X be 363-x
(X-3)*8/9=(363-X-3)
8X-24=3240-9X
17X=3264
X=192
A: the first one is 192 meters long

The length of the two wires is 363 meters. If the length of each wire is 3 meters, the length of the second wire is equal to one eighth of the length of the first wire?

The first length after cutting: (363-3-3) / (1 + 1 + 1 / 8) = 168m
The original length of the first one: 168 + 3 = 171 meters
The original length of the second one: 363-171 = 192m

The first wire is 10 meters longer than the second wire. After using both wires for 3 meters, the first wire is three times as long as the second wire. How many meters are there in each wire

Now the second one = 10 ÷ (3-1) = 5m
The original second one = 5 + 10 = 15m
The first one is 15 + 10 = 25m

After cutting a piece of iron wire by 5 / 9 meters, the rest is 14 / 3 meters less than the one cut. How long is the iron wire?
fast

5/9-3/14+5/9
=70/126-27/126+70/126
=113 / 126 M

There are two iron wires, one is 36 meters long and the other is 24 meters long. They are divided into small sections of the same length. How long is each section? How many sections can they be divided into?
+Formula

The greatest common divisor of 36 and 24 is 12
（36+24）/12=5
It can be divided into 12 meter segments, which can be divided into 5 segments

There are three iron wires, one is 24 meters long, one is 32 meters long, and the other is 16 meters long. Cut them into small sections of the same length. How long is each section at most?
Better not be too complicated

Because the greatest common factor of 24, 32 and 16 is 8
therefore
The maximum length of each section is 8 meters

There are three iron wires, one is 24 meters long, one is 32 meters long, and the other is 16 meters long. They are divided into small sections of the same length. How long is each section at most?

The greatest common factor of 24, 32, and 16 is 8, 24 △ 8 = 3 (segment); 32 △ 8 = 4 (segment); 16 △ 8 = 2 (segment); answer: the longest segment is 8m

There are two wires, one 36 meters long and the other 42 meters long. They are divided into small sections of the same length, each of which is several meters long at most

36=6x6
42=6x7
The greatest common divisor is 6
So the longest is 6 meters

The total length of the two wires is 33 meters. The first wire takes 3 / 2, the second wire takes 12 meters, and the remaining length of the second wire is that of the first wire
1 / 2 of the original length of the two wires

Assuming that the first one is useless, the second one will be 1 / 2 △ 1 / 3 = 1 / 6 of the first one after 12 meters, that is, divide the rest into 7 parts, (33-12) / (6 + 1) = 3 meters, then the length of the second one is 12 + 3 = 15 meters, and the length of the first one is 33-15 = 18 meters
