Perimeter of a kite

Perimeter of a kite is the distance around the outside of a kite and is calculated by adding the length of all its sides together.

Perimeter of a rectangle

P = A + B + C + D

Where P is the perimeter and A, B, C, and D are the kite’s sides.

Since a kite has 2 pairs of adjacent side congruent, the perimeter can be calculated by the following formula:
P = 2 × A + 2 × C
Where P is the perimeter, and A and C are the kite’s sides.

Note:
A = B and C = D

Example:
If A = 3, B = 3, C = 5, and D = 5
then P = ?

P = A + B + C + D = 3 + 3 + 5 + 5 = 16
or
P = 2 × A + 2 × C = 2 × 3 + 2 × 5 = 6 + 10 = 16
