First, let’s find out the length of the board in dm:
3 m 2 dm = 32 (dm) -Board length
To find the area, you need to multiply the length by the width, respectively:
32 * 4 = 128 (dm squared) – Area
The perimeter is the sum of all sides, respectively:
32 + 4 + 32 + 4 = 72 (dm) – Perimeter
Answer: S = 128 dm squared, P = 72 dm.
