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 centimetre find the length of each side of a triangle.

Answer 1

Given that , Equal side is twice the third side. Let the equal side be 'a'. Let the third side be 'b'. a=2b.  Perimeter =30 cm. a+a+b=30 2b+2b+b=30 5b = 30 b = 6 cm a = 2b = 2×6= 12cm Length of each side of a triangle is 6 cm, 12 cm, 12 cm.   That set

Answer 2

Answer:

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
