The length of a rectangular piece of land is 43 meters, and its width is 15 meters less than the length, find the perimeter and area of the site?
Find the width of this rectangular area.
According to the condition of the problem, the length of this rectangular piece of land is 43 meters, and the width of this one is 15 meters less than its length, therefore, the width of this section is:
43 – 15 = 28 m.
We find the perimeter p of a given rectangular section as the doubled sum of the length and width of this section:
p = 2 * (43 + 28) = 2 * 71 = 142 m.
Answer: the perimeter of this rectangular section is 142 m.
