image is the question plz help asap

B  =  (5, 5)

A  = (2, 1)

Subtract the x coordinates  =  (5 - 2) =  3 ...  square this  = 9

Subtract the y coordinates  = ( 5 - 1)  = 4 .....  square this   =  16

Add  the two results   9 + 16   =  25

Take the square root of this  = 5 units  =  the distance between  A and B
