1) First you need to find the length of the rectangle:
8 * 3 = 24 dm.
2) The formula for finding the area of a rectangle is:
S = a * b, where a and b are the sides of the rectangle.
24 * 8 = 192 dm².
3) The formula for finding the perimeter of a rectangle is:
S = 2 (a + b), where a and b are the sides of the rectangle.
2 (24 + 8) = 2 * 32 = 64 dm.
Answer: 192 dm²; 64 dm.
