Question

–Each of the two 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:

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.
