what is the perimeter of rectangle jklm?
32 units
44 units
56 units
64 units

Third option.

Step-by-step explanation:

The missing figure is attached.

The perimeter of a rectangle can be calculated with:

Where "l" is the length and "w" is the width.

We can see that the width of this rectangle is:

So, we need to find the lenght.

Let be P the point  of intersection of the diagonals.

The diagonals of a rectangle are equal.

Since:

We know that, by definition:

Then, we can find the lenght of the rectangle by using the Pythagorean Theorem:

We can identify that:

Then, subsituting values and solving for "LM", we get:

Substituting values into the formula for calculate the perimeter, we get:
