- Let the length of equal sides be x cm Perimeter = x cm + x cm + Base = 4 2/15 cm
- 2x + 4/3 = 62/15
- On transposing 4/3 to R.H.S,
- we obtain 2x = 62/15 - 4/3 2x = 62 - 4 x 5/15 = 62 - 20/15 2x = 42/15
- On dividing both sides by 2, we obtain 2x/2 = 42/15 x1/2 x = 7/5 = 1 2/5
- Therefore,
the length of equal sides is 1 2/5 cm.
