The length a of the rectangular section is 15 meters.
The width b of this section is 7 meters less than its length.
Let’s calculate the width b:
b = a – 7 = 15 – 7 = 8 meters.
Let’s find the perimeter of the site using the formula P = a + a + b + b:
P = a + a + b + b = 15 + 15 + 8 + 8 = 46 meters.
Answer: the perimeter of the site is 46 meters.
