The length of the rectangular section is 43 m, and its width is 15 m less than the length. Find the subject and area of the lot.

The plot, the dimensions of which are given, will be considered as a rectangle. Let the length be D, and the width – W. Then W = D – 15 = 43 – 15 = 28 m. Now you can calculate the perimeter. In our case, it will be expressed as follows:

R = 2 * D + 2 * W = 2 * 43 + 2 * 28 = 142 m

Using the formula S = D * W, we define the area:

S = 43 * 28 = 1204 m2

Answer: the plot has a perimeter of 142 m, and its area is 1204 m².
