The length of the room is 8 m, and the width is 2 m less. Find the perimeter and area of the room.

1) Determine the width of the room, provided that it is 2 m less than the length equal to 8 m:

8 – 2 = 6 m.

2) The perimeter of a rectangle whose opposite sides are equal is calculated by the formula:

P = 2a + 2b = 2 * 8 + 2 * 6 = 16 + 12 = 28 m.

3) The area of such a figure corresponds to the formula:

S = a * b = 8 * 6 = 48 m².
