we are given that

both sides are equal

so, their length must be equal


HK=√((p-1)^2+(5-2)^2)


HK=√((p-1)^2+9)

now, we can find other side


JK=√((p-7)^2+(5-2)^2)


JK=√((p-7)^2+9)

now, we can set them equal


HK=JK


√((p-1)^2+9)=√((p-7)^2+9)

now, we can take square both sides


(p-1)^2+9=(p-7)^2+9

now, we can solve for p


(p-1)^2=(p-7)^2


p^2-2p+1=p^2-14p+49


-2p+1=-14p+49


12p=48


p=4..............Answer
