Join Point A and B with a straight line .You have to find the length of this line AB
After joining the AB the figure formed is a right angled triangle
We are given the length of two sides AC and BC and we have to find the length of the 3rd side AB
Apply pythagoras theorem for that:
AB² = AC² + BC²
AB² = 1600 + 1681
AB² = 3281
AB = 57 approx
