Question

The perimeter of an isosceles triangle is 32 cm. The ratio of the equal side to its base is 3:2.
Find the sides of that triangle.

Answer 1

Perimeter of an isosceles triangle = 32 cm
Ratio = 3 : 2
From the given ratio we get, a = 3x,
b = 3x and c = 2x

Now we can write,
3x + 3x + 2x = 32
Therefore, 8x = 32
$\Rightarrow$ x = 4

Therefore, sides of triangle are a = 12 cm, b = 12 cm, c = 8 cm
