The rectangle is 84 m wide, which is 6 m less than its length. Find the permetri and area of this rectangle.

1. If the width of the rectangle is 6 meters less than the length, then the length is correspondingly greater than the width by the same number of meters. Let’s find it:

84 + 6 = 90 (m).

2. Now we find the perimeter of this rectangle, which, as you know, is equal to the sum of twice the width and twice the length:

2 x 84 + 2 x 90 = 348 (m).

3. Finally, we calculate the area of this rectangle by multiplying its length by width:

90 x 84 = 7560 (m²).

Answer: the perimeter of the specified rectangle is 348 meters, and its area is 7560 square meters.
