Question

Each of the 2 equal sides of an isosceles triangle is twice as large as the third side. If
the perimeter of the triangle is 30 cm, find the length of each side of the triangle

Answer 1

Answer:

Let third side = X

Each of equal sides = 2X

A/q,

X+2X+2X = 30

5X = 30

X = 6

Third side = 6cm

Each of equal sides = 12 cm
