Question

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

Answer 1

Answer:

6cm,12cm,12cm let sides be x,x,y then x=2y and 2x+y=30 solving you get it

Answer 2

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
