Question

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 1

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
