As shown in the figure, four identical rectangular floor tiles and one side length of 60cm
As shown in the figure, four identical rectangular floor tiles and a square floor tile with a side length of 60cm are laid into a large square with a side length of 80cm. Try to find out the length and width of the rectangular floor tile
To solve a quadratic equation of two variables
As shown in the picture
Let length and width be x, y, respectively
x+y=80(1)
x-y=60(2)
By combining (1) and (2), a system of quadratic equations with two variables is obtained,
The solution is x = 70, y = 10
It is 70cm long and 10cm wide
A kind of rectangular floor tile is 60cm long and 42cm wide. How many pieces does it take to make a square floor with such tiles?
The greatest common divisor of 60 and 42 is 6, so the side length is 6cm (60 ﹣ 6) × (42 ﹣ 6) = 70 pieces. Please click "adopt as the answer"
Decoration workers to a house floor tile, if the side length of 40cm square brick shop, need 300. If the side length of 50cm square brick, how much
It would be better if we could solve the equation~
192 bricks. 160 * 300 / (50 * 50)
It costs 16.8 yuan for each tile with a side length of 40 cm, 13.5 yuan for each square meter of floor, and 28 yuan for each tile with a side length of 50 cm
What kind of floor tile costs less?
For a square, 16.8 ÷ (0.4 * 0.4) + 13.5 = = 105 yuan per square
28 ÷ (0.5 * 0.5) + 12.5 = = = 124.5 per flat
Xiao Ming found that if the 40cm * 40cm floor tile is used for the living room, it needs 75 pieces. If the 50cm * 50cm floor tile is used for the living room, how many pieces are needed? What about the 30cm * 30cm floor tile? If the floor tile is x ^ 2, what is the relationship between the number of floor tiles y and X?
40*40*75=X*50*50,
