The circumference of a rectangle is 36 cm, and the length is 10 cm. The simplest integer ratio of length and width is______ ．
The width is 36 △ 2-10, = 18-10, = 8 (CM); the ratio of length and width is 10 cm: 8 cm = 10:8 = (10 △ 2): (8 △ 2) = 5:4; so the answer is: 5:4

The circumference of a rectangle is 100 cm, when the length of the rectangle is reduced by 10 cm
The circumference of a rectangle is 100 cm. When the length of the rectangle is reduced by 10 cm and the width is increased by 10 cm, the rectangle just becomes a square. How much is the length and width of the original rectangle
linear equation in two unknowns
Let the length be xcm and the width be YCM
According to the meaning of the title
x+y=100
x-10=y+10
Solution
x=60
y=40
The original rectangle is 60cm long and 40cm wide
