The area of a rectangular section is 600 square meters, its length is 30 m.

The area of a rectangular section is 600 square meters, its length is 30 m. How many meters is the width of this section less than its length?

Site area – 600 m ^ 2;

Length (a) – 30 m;

Width (b) -? m;

The width is less than the length – by? m.

The area of the site is expressed by the formula: Spr = a * b;

Then we express from it the unknown value of the width and find it:

b = Spr: a = 600: 30 = 20 (m).

To answer the question of the problem, we subtract the value of its width from the value of the length of the section, we get:

30 – 20 = 10 (m).

Answer: the width of the section is 10 m less than its length.
