Question

8. Периметр рівнобедреного трикутника дорівнює 48 см. Довжина основи 3/8Яку частину периметра становить довжина бічної сторони.

Answer 1

48 ÷ 8 × 3 = 18 см - основание треугольника

(48-18)÷2 = 15 см - длина боковой стороны

15/48= 5/16 - от периметра составляет боковая сторона

Answer 2

Perimeter of an Isosceles Triangle

To find the portion of the perimeter represented by the length of the base of an isosceles triangle, we can use the formula for the perimeter of a triangle and then calculate the portion represented by the length of the base.

The formula for the perimeter of a triangle is: Perimeter = 2 * base + side

Given that the perimeter of the isosceles triangle is 48 cm and the length of the base is 3/8 of the perimeter, we can calculate the length of the side using the given information.

Calculation

Using the given information: - Perimeter of the isosceles triangle = 48 cm - Length of the base = 3/8 * Perimeter

We can calculate the length of the base and the side using the given information.

Solution

The length of the base of the isosceles triangle: Length of base = 3/8 * 48 cm = 18 cm

Now, we can calculate the length of the side using the formula for the perimeter of a triangle: 48 cm = 2 * 18 cm + side

Solving for the length of the side: 48 cm = 36 cm + side side = 48 cm - 36 cm = 12 cm

Conclusion

The length of the base of the isosceles triangle is 18 cm, and the length of the side is 12 cm. Therefore, the portion of the perimeter represented by the length of the base is 18 cm, and the portion represented by the length of the side is 12 cm.
