The circumference of an isosceles triangle is eighteen centimeters, and the ratio of the two sides is five to two. How many centimeters is the length of the bottom side

18 △ 12 = 1.5 times 5,5,2

The circumference of an isosceles triangle is 18 cm 1. The length of the waist is 3 times more than the length of the bottom 2. The length of each side is 13 cm. The length of one side is 5 cm. The length of the other sides is 13 cm

1. If the bottom edge is x cm and the waist length is (13 + 2x) / 3, then: x + (13 + 2x) / 3 × 2 = 183x + 26 + 4x = 547x = 28x = 4 (18-4) △ 2 = 7 cm, the waist length is 7 cm, the bottom edge is 4 cm 2, and one side is 5 cm

The sides of an isosceles triangle are 5cm and 2cm respectively, and its circumference is () cm

The three sides of this isosceles triangle can only be 5cm, 5cm and 2cm
The circumference is 5 + 5 + 2 = 12 cm
