An isosceles triangle is a triangle with the same lateral sides. We know the base of the triangle and its perimeter, so we can find the sum of the same sides:
a + a = 2.5 m – 1.3 m = 1.2 m – the sum of the sides;
Now let’s find the side of an isosceles triangle:
a = 1.2 / 2 = 0.6 m = 60 cm
Answer: 60 cm
