f with coordinates J( 6,4), K-1 a 50 b. 15 c. 40 d. 30 e. None correct 12. Find the value of j 9 a. 21 b. 49 c. 42 d. 27

11. The perimeter is given by sum of lengths of sides.

So, JK + KL + LM + MJ

= 2*(LM+MJ)

LM = sqrt((-16+6)^2 + (-1+1)^2) = 10

MJ = sqrt((-6+6)^2 + (4-(-1))^2) = 5

So, total perimeter = 2 *(10+5) = 30 m

D is the right option
