A rectangle-shaped plot adjoins the house, the length of which is 10 m, on 3 sides the plot is fenced

A rectangle-shaped plot adjoins the house, the length of which is 10 m, on 3 sides the plot is fenced with a length of 130 meters. What is the area of this site.

Since one of the sides of the plot is the wall of the house, it means that the rest of the perimeter of the plot, which is fenced, consists of 2 equal parts and one part, which is 10 meters.

In this case, the sum of the lengths of the sides of the fence of two equal parts will be equal to:

130 – 10 = 120 meters.

The length of one part will be:

120/2 = 60 meters.

In order to determine the area of the site, it is necessary to multiply its length and width among themselves.

We get:

10 * 60 = 600 m ^ 2.

Answer: The area of the plot is 600 m ^ 2.
