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:

Hope you find it good Buddy...

Step-by-step explanation:

let two sides be 2X

and the third one be x

Now,

According to Question,

Perimeter=30cm

Therefore,

2x+2x+x=30

5x=30

x=6cm

Hence, Length of two equal sides are 12 cm

and third side is 6cm

Answer 2

Answer:

Step-by-step explanation:

Let the third side be x cm.

Other two sides=twice of third side=2x cm and 2x cm.

Perimeter=30cm.

Formula of perimeter :sum of three sides.

Therefore,X+2x+2x=30cm X+4x=30cm 5x=30cm X=30/5 X=6.

1st side of triangle=6

Second side of triangle=2x=6*2=12

Third side of triangle=2x=6*2=12.
