A. 20 mm
B. 22 mm
C. 18 mm
D. 15 mm
That's Correct!
It's Wrong!

To find the perimeter, we need to add the lengths of all the sides of the shape.

Let’s look at the given shape.

Add the lengths of all the sides.

7 + 4 + 7 + 4 = 22

As the lengths are measured in millimeters, the perimeter is also measured in millimeters.

So, the perimeter of the given shape is 22 mm.
