Two rectangular sections have the same area. The first section is 48 m long and 18 m narrower.

Two rectangular sections have the same area. The first section is 48 m long and 18 m narrower. Find the perimeter of the second section if it is 6 m wider than the first section.

First of all, we calculate the width of the section, subtracting 18 m from the length of the section:

48 – 18 = 30 (m).

Let’s find the area of this site, multiply its length by width:

S = 48 * 30 = 1440 (m²).

Now we find the width of the second section if its width is 6 m greater than the width of the first section:

30 + 6 = 36 (m).

We calculate the length of the second section, dividing the area by the width:

1440: 36 = 40 (m).

Now let’s answer the question to the problem, calculate the perimeter of the second section:

P = 2 (40 + 36) = 152 m.

Answer: the perimeter of the second section is 152 m.
