1.	two equal sides of an isosceles triangle are each 2 cm more than thrice the third side if the perimeter of triangle is 67 cm find the length of its sides
Answer» Answer: LET the lenght of the THIRD side be x. then remaining TWO equal SIDES are 3x+2 , 3x+2. perimeter of a trainagle = sum of three sides as per the PROBLEM, x+3x+2+3x+2 = 67 7x + 4 = 67 7x = 67 - 4 7x = 63 x = 63/7 x = 9. therefore sides are 9 cm ,(39+2)cm,(39+2)cm = 9 cm, 29cm, 29cm

two equal sides of an isosceles triangle are each 2 cm more than thrice the third side if the perimeter of triangle is 67 cm find the length of its sides

Answer»

Answer:

LET the lenght of the THIRD side be x.

then remaining TWO equal SIDES are 3x+2 , 3x+2.

perimeter of a trainagle = sum of three sides

as per the PROBLEM,

x+3x+2+3x+2 = 67

7x + 4 = 67

7x = 67 - 4

7x = 63

x = 63/7

x = 9.

therefore sides are 9 cm ,(3*9+2)cm,(3*9+2)cm = 9 cm, 29cm, 29cm
