The length of the rectangle is 6cm and the width is 2cm less. Find the area and perimeter of the rectangle.

The area of the rectangle is calculated by the formula:

S = a * b.

Let us find this value, provided that the width of such a figure is 2 cm less than its length, equal to 6 cm:

S = 6 * (6 – 2). According to the order of performing mathematical operations, first of all we find the values in brackets:

S = 6 * 4 = 24 cm².

The perimeter is determined by the formula:

P = 2a + 2b. Substitute the dimensions of the rectangle:

P = 2 * 6 + 2 * 4 = 12 + 8 = 20 cm.
