| Let’s define the perimeter and area of a square plot of land with a side length of 8 m 5 dm. First, we translate the value into decimeters.

1 m – 10 dm.

8 m 5 dm = 8 × 10 + 5 = 80 + 5 = 85 dm.

We find the perimeter of the square area. The perimeter is the sum of the lengths of all sides.

P = 4a = 4 × 85 dm = 340 dm.

The perimeter is 340 decimeters.

We find the area.

S = a ^ 2 = (85 dm) ^ 2 = 7225 dm ^ 2.

This means that the area of a square plot of land is 7225 dm ^ 2.

Answer: P = 340 dm. S = 7225 dm ^ 2.
