1.	3. The perimeter of an isosceles triangle is 65 cm and the unequal side is thrice as large as each ofthe equal sides. Find the lengths of the sides of the triangle
Answer» Let the sides of given isosceles triangle arex, x and 3x Then,Perimeter of triangle =x + x + 3x Thus,5x = 65x = 65/5 = 13 cm Therefore sides of triangle are 13 cm, 13 cm and 39 cm

3. The perimeter of an isosceles triangle is 65 cm and the unequal side is thrice as large as each ofthe equal sides. Find the lengths of the sides of the triangle

Answer»

Let the sides of given isosceles triangle arex, x and 3x

Then,Perimeter of triangle =x + x + 3x

Thus,5x = 65x = 65/5 = 13 cm

Therefore sides of triangle are 13 cm, 13 cm and 39 cm
