| 1. First, calculate the length of the rectangle, which is 5 times the width:
4 x 5 = 20 (cm).
2. Now you can calculate the perimeter of the declared rectangle using the formula:
P = 2 x A + 2 x B,
where A is the length of the rectangle, B is its width.
P = 2 x 20 + 2 x 4;
P = 88 (cm).
Answer: the perimeter of the declared rectangle is 88 cm.
