240m = 24000cm 24000/3000 = 8cm
150m = 15000cm 15000/3000 = 15cm
8 cm long and 0/5 cm wide.
Rectangular wheat field, perimeter150m, length-width ratio of 3: 2. What is the area of this wheat field?
150/2 = 75m
3+2=5
75 * 3/5 = 45 meters
75 * 2/5 = 30m
45 * 30 =1350m2
In a field with a length of 30m and a width of 12m, tomatoes, cucumbers and eggplants are planted, among which tomatoes account for 5/ 12 of the total area, and the rest are 3: 2 kinds of cucumbers and eggplants. How many square meters should cucumber and eggplant be planted respectively?
30 *12 = 360m2
360 * 5/ 12 = 150 m2
360- 150 = 2 10 m2
3+2=5
2 10 * 3/5 = 126 m2
2 10 * 2/5 = 84 square meters
Tomato 150 m2, cucumber 126 m2 and eggplant 84 m2.
