ABCD – rectangle;
Side BC = 5 centimeters;
Side AB -? centimeters, 2 centimeters less than BC,
Perimeter -? centimeters.
First, we find the length of the side AB:
5 – 2 = 3 (centimeters) – length AB;
We find the perimeter by the formula: (a + b) × 2, where
a – BC,
b – AB, therefore
(5 + 3) × 2 = 16 (centimeters).
Answer: Perimeter ABCD = 16 centimeters.
