A triangle has a perimeter of 91 centimeters. Each of the two longer sides of the triangle is three times as long as the shortes t side. Find the length of each side of the triangle.
1 answer:
9514 1404 393
Answer:
13 cm, 39 cm, 39 cm
Step-by-step explanation:
If x is the short side, then the other two sides are 3x and 3x. The perimeter is the sum of side lengths:
x +3x +3x = 91
x = 91/7 = 13
3x = 3(13) = 39
The length of the short side is 13 cm; the other two sides are 39 cm .
