Question

Периметр равно бедреного треугольника АВС равен 30 см , а одна из сторон на 3 см больше другой . Какими могут быть стороны треугольника АВС ?

Answer 1

(30-3):3=9 см две стороны
9+3=12 см третья сторона

Answer 2

Calculating the sides of the triangle ABC:

The perimeter of the triangle ABC is given as 30 cm. We are also told that one side is 3 cm longer than the other.

Let's call the shorter side x cm. Then the longer side must be x + 3 cm. We can set up an equation for the perimeter:

x + (x + 3) + z = 30 2x + 3 + z = 30 2x + z = 27

Since the perimeter is a whole number, x and z must also be whole numbers that sum to 27. The only possible values are:

x = 9 cm z = 18 cm Longer side = x + 3 = 12 cm

Therefore, the possible sides of triangle ABC are:

a = 9 cm b = 12 cm c = 18 cm
