A triangular vegetable field has a side length ratio of 3:4:5 and a perimeter of 48 meters. How many meters is the shortest side of the triangle?

A triangular vegetable field has a side length ratio of 3:4:5 and a perimeter of 48 meters. How many meters is the shortest side of the triangle?

48 ÷ (3 + 4 + 5) = 4m
The shortest side of this triangle is 4 × 3 = 12 meters

A triangle vegetable field, side length ratio is 3:4:5, perimeter is 60 meters, the shortest side length () meters

Let the side length be 3k, 4K and 5K respectively
According to the meaning of the title
3k+4k+5k=60
k=5
So the shortest side length is 3K = 15 (m)
A: the shortest side length is 15 meters

If the two sides of a triangle are 5 cm and 8 cm respectively, the length of the third side may be () cm
A. 12 cm B. 13 cm C. 14 cm

According to the trilateral relationship of the triangle, the third side should be greater than 8-5 = 3, and less than 8 + 5 = 13, 3 < the third side < 13
