The difference between the length and width of a rectangular section is 240 cm, and the length is 3 times less than the perimeter of 1440 m. Calculate the area of this section.
Find the length of the rectangle.
We divide the specified perimeter by the specified ratio, namely 3.
We get:
1440/3 = 480 meters.
We find the sum of the length and width of this rectangular section.
Divide the specified perimeter by 2.
1440/2 = 720 m.
Since the length is 480 m, and the sum of the length and width is 720 m, then the width will be:
720 – 480 = 240 m.
From this it follows that the area of the site is equal to:
480 * 240 = 115200 m2
We translate the value of the area into ares.
115200/100 = 1152 amu.
Answer: 1152 a.
