Answer:
Perimeter = 13.27 unit
Step-by-step explanation:
We have to find the perimeter of the shape given in the figure.
Coordinates of J are ( -3, 4 ) and K are (-1, 6)
Then JK = 
= 
= 
= 
Coordinates of K are (-1,6) and for ∠ are (1, 1)
KL = 
= 
= 
Coordinates of M are (-1, 3) and of ∠ are (1, 1)
∠M = 
= 
= 
Coordinates of M are (-1, 3) and J are (-3, 4)
MJ = 
= 
= 
Then perimeter = JK + KL + LM + MJ
=
+
+
+ 
=
+
+ 
= 5.66 + 5.38 + 2.24 = 13.27
