The area of a rectangle is the width times the length:

The perimeter is twice the sum of the dimensions:

Answer:
A
Step-by-step explanation:
The only side that you dont have to use the Pythagorean theorem is LQ and that measure is 2. So A is the correct answer.
Given:
A figure of a circle.
.
To find:
The length of KJ.
Solution:
From the given figure it is clear that the number 6 is marked between K and J it means the number 6 represents the distance between the points K and j.
Therefore, the length of KJ is 6 units.
Note: In the given question we need to find KL instead of KJ because KJ is already given.
According to the tangent secant theorem:

Where,
- a is the length of the tangent.
- b is the length of the external segment of the secant.
- c is the measure of the secant.
Using the tangent secant theorem, we get




On further simplification, we get



Splitting the middle term, we get




For
,

, which is not possible because side cannot be negative.
For
,


Therefore, the measure of KL is 2 units.
