Question

Find the distance between the points R(-3,a),S(a,-2a)​

Answer 1

Step-by-step explanation:

We have to find the distance between the points R(a + b ,a - b) and S(a - b, - a - b).

Using distance formula, we obtain

RS = (a−b−a−b)2+(−a−b−a+b)2−−−−−−−−−−−−−−−−−−−−−−−−√= 4b2+4a2−−−−−−−−√=2a2+b2−−−−−−√

Answer 2

Step-by-step explanation:

We have to find the distance between the points R(a + b ,a - b) and S(a - b, - a - b).

Using distance formula, we obtain

RS = (a−b−a−b)2+(−a−b−a+b)2−−−−−−−−−−−−−−−−−−−−−−−−√= 4b2+4a2−−−−−−−−√=2a2+b2−−−−−−√
