Triangle CDE in the picture has two 6-inch sides and a long diagonal side that's about 8.5 inches (a bit longer than 6). Just add them up, and you get a perimeter of roughly 20 inches! Think of it like putting three big building blocks (6 inches each) together with a longer one on top (about 8.5 inches), making a big border around them.

Sure, based on the image you sent, the perimeter of triangle CDE is 12 inches.

Since triangle CDE is a right triangle, the perimeter can be found by adding the lengths of all three sides. From the image, we can see that:

Side CD = 6 inches

Side DE = 6 inches

Side CE (the hypotenuse) = 6√2 inches (using the Pythagorean theorem)

Therefore, the total perimeter is:

Perimeter = CD + DE + CE

Perimeter = 6 inches + 6 inches + 6√2 inches

Perimeter ≈ 6 inches + 6 inches + 8.49 inches

Perimeter ≈ 20.49 inches

Rounding to the nearest whole inch, the perimeter of triangle CDE is 20 inches.
