Perimeter of an Isosceles Triangle

To find the sides of an isosceles triangle given its perimeter and the length of one of its sides, we can use the following steps:

1. Let's assume that the length of the base of the triangle is x cm. 2. According to the given information, the perimeter of the triangle is 17 cm. Since the base is 2 cm longer than one of the equal sides, we can express the perimeter as follows: - Perimeter = length of base + 2 * length of equal side - 17 = x + 2 * (x - 2) 3. Simplifying the equation: - 17 = x + 2x - 4 - 17 = 3x - 4 - 3x = 21 - x = 7 4. Now that we have the length of the base, we can find the length of the equal sides: - Length of equal side = x - 2 = 7 - 2 = 5 cm

Therefore, the sides of the given isosceles triangle are 5 cm, 5 cm, and 7 cm.
