| **A square with a side is given.How will the area of the resulting figure change if one side of the square is increased by 1 m and the other is reduced by the same amount.**

S sq. = a * a = a² (m²).

After changing the parameters of the side of the square, we get a rectangle shape with sides:

(a + 1) m – length;

(a – 1) m – width.

We find the area of the rectangle by the formula:

S straight. = (a + 1) * (a – 1) = a² – 1 (m²).

S sq. > S straight

a² – (a² – 1) = 1 (m²).

Answer: the area of the resulting rectangle is less than the area of the square by 1 m².
