The rectangle is 8 m long and 3 dm shorter. Find the perimeter and area of this rectangle.

To find the perimeter and area of a rectangle, you first need to find the width of the rectangle.

To do this, we will convert all lengths to decimeters:

The length of the rectangle is 8 m, since there are 10 dm in one meter, we multiply by 10: (8 * 10 = 80)

Now we calculate the width, subtract 3 from the length: (80 – 3 = 77);

We calculate the perimeter, add the length and width and multiply by 2: (80 + 77) * 2 = 314;

We calculate the area, multiply the length by the width: (80 * 77 = 6160).

Answer: The area is 6160 dm .;

The perimeter is 314 dm.
