Answer: 3) is the right option. The perimeter of given isosceles trapezoid is
units
Step-by-step explanation:
In the given diagram a isosceles trapezoid KLMN is given with sides KL= 2√2 units , LM= √5 units and MN=√2units
To find the perimeter we need all the sides of the isosceles trapezoid i.e.we need to find KN with coordinates K=(-2,-4) and N=(-1,-2),by distance formula [distance between two points =
]
KN=
OR as it is a isosceles trapezoid then two of its opposite sides must have have same length. as KL≠MN then LM must be equal to KN.
Now the perimeter of KLMN=KL+LM+MN+KN=
units.
