Question

The perimeter of an isosceles triangle is 14 cm. One of its sides is twice longer than another of its sides. Find all sides of the triangle.

Answer 1

Explanation:

2.8, 5.6, 5.6

Answer 2

An isosceles triangle has 2 equal sides so the 3 sides = a a and b
The side that is twice longer than another side make it equal 2*a.
So the total of the 3 sides would equal 14
4a = 14
So 2 sides = 3.5 and the third side = 7.
3.5 + 3.5 + 7 = 14
