The length of the rectangle is 68m, and the width is 4 times less. Find the pyrometer and the area of this rectangle.

First of all, we find the width of the rectangle if it is 4 times less than the length equal to 68 m:
68: 4 = 17 (m).
We calculate the perimeter of a rectangle with sides of 68 m and 17 m, which is equal to twice the sum of the two sides of the rectangle:
P = 2 (68 + 17) = 2 * 85 = 170 (m).
Now we find the area of a rectangle with sides of 68 m and 17 m, which is equal to the product of its length and width:
S = 68 * 17 = 1156 (m²).
Answer: the perimeter of the rectangle is 170 m, and the area of the rectangle is 1156 m².
