Answer:-3 3/5 <1.3
Step-by-step explanation:
Perimeter of the equilateral triangle KLM with vertices K(-2 ,1) and M (10,6) is equal to 39 units.
As given in the question,
Coordinates of vertices K(-2,1) and M(10,6)
KM = ![\sqrt{ (10-(-2)^{2} +(6-1)^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%20%2810-%28-2%29%5E%7B2%7D%20%2B%286-1%29%5E%7B2%7D%20%7D)
= ![\sqrt{12^{2}+5^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B12%5E%7B2%7D%2B5%5E%7B2%7D%20%20%7D)
= 13units
In equilateral triangle KL = LM = KM = 13 units
Perimeter of equilateral triangle KLM = 13 +13 +13
= 39 units
Therefore, perimeter of the equilateral triangle KLM with vertices K(-2 ,1) and M (10,6) is equal to 39 units.
