Use a piece of rectangular red cloth 40 cm long and 30 cm wide to make a right triangle flag. The two right angles of the flag are 10 cm and 5 cm respectively. How many such flags can this cloth make at most?
(40 ／ 10) × (30 ／ 5) × 2, = 4 × 6 × 2, = 48; a: you can make up to 48 such flags
There is a rectangular red cloth 4 meters long and 80 cm wide, which is made into a small flag of isosceles right triangle. How many such small flags can be made on the right side of the flag
If you make 100 such small red flags, how much red cloth do you need
4m = 400cm
400÷80＝5
2 × 5 = 10 (surface)
To make 100 such small red flags, you need 4 × 0.8 × 10 = 32 square meters
Use a piece of red cloth 4 meters long and 80 cm wide to make a small flag of isosceles right triangle. The right angle side length of the small flag is 20 cm. How many flags can be made at most?

A piece of red cloth 3 decimeters long and 2 decimeters wide can be made into at most how many right triangle flags with a bottom of 5 cm and a height of 4 cm?
Come on,
lilytrtr,
3DM = 30cm, 2DM = 20cm
At most:
（30÷5）×（20÷4）×2
＝6×5×2
= 60 pieces
With a piece of 4 meters long, 80 cm wide rectangular red cloth to make a kind of isosceles right triangle flag, the right angle side of the flag is 20 cm long, how many such flags can be made at most?
4x0.8÷(0.2x0.2÷2)=160
