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 40 cm, find the length of each side of the triangle.​

Answer 1

Step-by-step explanation:

Other two sides=twice of third side=2x cm and 2x cm. Perimeter=30cm. Formula of permiter:sum of three sides. Therefore,X+2x+2x=30cm X+4x=30cm 5x=30cm X=30/5 X=6.

Answer 2

Step-by-step explanation:

Other two sides=twice of third side=2x cm and 2x cm. Perimeter=30cm. Formula of permiter:sum of three sides. Therefore,X+2x+2x=30cm X+4x=30cm 5x=30cm X=30/5 X=6.
