The plot of land has the shape of a rectangle with a width of 1200 cm, which is 3 m less than its length.

The plot of land has the shape of a rectangle with a width of 1200 cm, which is 3 m less than its length. It is wired in 6 rows. How many meters of wire did you need?

1. We translate the units of length:

1 meter = 100 centimeters;

1 200 cm = 12 meters – the width of the site.

2. Determine the length of the rectangular section:

12 m + 3 m = 15 m.

3. Determine the perimeter of the rectangular area:

P = 2 x (12 m + 15 m) = 2 x 27 m = 54 m.

4. Determine the required wire footage for this section:

54 mx 6 rows = 324 m.

To enclose the site, 324 m of wire were required.
