Question

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

Answer 1

Step-by-step explanation:

let the 3rd side be x

so one equal side will be 3x+2

we know that perimeter of triangle = sum of all the side

so

67= (3x+2)(2)+ x ( as there are two equal side in isosceles triangle)

67= 6x+4+x

63= 7x

x = 63/7= 9

so 3rd side will be 9 cm

and the two equal side will be of 3x+2 = 27+2 = 29cm
