Let the second side be a
First side = 2a
Third side = a + 2
Perimeter = a +2a + a + 2
=> 4a + 2 = 34
=> 4a = 32
=> a = 8
First side = 2 × 8 = 16 cm
Second side = 8 cm
Third side = 8 + 2 = 10 cm
First side = 2a
Third side = a + 2
Perimeter = a +2a + a + 2
=> 4a + 2 = 34
=> 4a = 32
=> a = 8
First side = 2 × 8 = 16 cm
Second side = 8 cm
Third side = 8 + 2 = 10 cm
