Problem Analysis

We are given that the perimeter of a triangle is 56 cm. One side of the triangle is equal to 5/14 of the perimeter, and another side is equal to 15/8 of the length of the other side. We need to find the lengths of the sides of the triangle.

Solution

Let's assume the lengths of the sides of the triangle are a, b, and c. We are given the following information: - The perimeter of the triangle is 56 cm. - One side of the triangle is equal to 5/14 of the perimeter. - Another side is equal to 15/8 of the length of the other side.

We can set up the following equations based on the given information: 1. a + b + c = 56 (equation for the perimeter) 2. b = (5/14) * 56 (equation for one side) 3. c = (15/8) * b (equation for another side)

To find the lengths of the sides, we can solve these equations simultaneously.

Substituting equation 2 into equation 3, we get: c = (15/8) * ((5/14) * 56)

Simplifying the expression: c = (15/8) * (5/14) * 56 c = (15/8) * 5 * 4 c = 75/8 * 4 c = 75/2

So, the length of side c is 75/2 cm.

Substituting the values of b and c into equation 1, we can solve for a: a + (5/14) * 56 + 75/2 = 56

Simplifying the equation: a + 20 + 75/2 = 56 a + 40 + 75/2 = 56 a + 75/2 = 16 a = 16 - 75/2 a = 32/2 - 75/2 a = -43/2

Since the length of a side cannot be negative, we can conclude that there is no valid solution for this triangle.

Therefore, there are no valid lengths for the sides of the triangle that satisfy the given conditions.
