The width of the rectangular section is 7 meters. What is the length of the site if the length of the fence around the site is 36 meters.
Let us denote by x the length of this rectangular section. According to the problem, the length of the fence around the site is 36 meters. Since the length of the fence around the site is equal to the sum of all four sides of the site, and the width of this rectangular area is 7 meters, we can write the following ratio:
x + 7 + x + 7 = 36.
We solve the resulting equation:
2 * x + 14 = 36
2 * x = 36 – 14
2 * x = 22
x = 22/2
x = 11
Answer: the length of this rectangular section is 11 meters.
