One side of an arbitrary isosceles triangle is 35 cm. The other side of this triangle is 3/5 of the third side of this triangle. Find the perimeter of this triangle.
To solve this problem, remember. that an isosceles triangle is a triangle in which two sides and two angles at the base are equal. We calculate what the base is equal to, knowing that it is 3/5 of the other side, equal to 35 centimeters.
35 * 3/5 = 105/5 = 21 centimeters.
The perimeter of a triangle is equal to the sum of the lengths of all three sides.
P = 35 + 35 + 21 = 91 centimeters.
Answer: 91 centimeters.
