One of the sides of the rectangle is 2.3 m, which is 3.4 m less than the adjacent one, calculate the perimeter and area.

To solve this problem, you first need to find the value of the second side of the rectangle.

Since the first side is 3.4 meters smaller than the second, the length of the second side will be:

2.3 + 3.4 = 5.7 meters.

We find the perimeter.

To do this, multiply the sum of the sides by 2.

We get:

2 * (2.3 + 5.7) = 2 * 8 = 16 m.

Find the area of the rectangle.

To do this, we multiply the sides of the rectangle with each other.

We get:

2.3 * 5.7 = 13.11 m ^ 2.

Answer:

The perimeter of the rectangle is 16 meters, the area of the rectangle is 13.11 m ^ 2.
