A triangle vegetable field, the ratio of side length is 3:4:5, perimeter is 84 meters, the shortest side length______ Rice
The total number of shares: 3 + 4 + 5 = 12 (shares), the shortest side length: 84 × 312 = 21 (meters); answer: the shortest side length is 21 meters
The perimeter of the triangle vegetable field is 168 meters, the ratio of side length is 4:3:5, and the longest side length is 5______ Rice
4 + 3 + 5 = 12168 × 512 = 70 (m) a: the longest side is 70 M
