Draw a rectangle which is 9 cm long and 1 3 times the length of the width. Subtract the perimeter and area of this rectangle.

Before finding the perimeter and area of the rectangle, we’ll start by calculating the length of the rectangle.

We know from the condition that the length of the rectangle is 9 cm, and we also know that the width is 1/3 of the length.

Let’s calculate the width of the rectangle:

9 * 1/3 = 3 cm.

Let’s remember and apply the formula for calculating the perimeter of a rectangle:

P = 2 (a + b).

Perimeter is the sum of the lengths of all sides of the rectangle.

P = 2 * (9 + 3) = 2 * 12 = 24 cm.

Now let’s calculate the area of the rectangle:

S = a * b = 9 * 3 = 27 cm ^ 2.
