what is the perimeter of a rectangle 8mm by 3m
The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the length is 12m and the width is 3m. Therefore, the perimeter would be 2(12m) + 2(3m) = 24m + 6m = 30m.
If you mean an area measuring 3m x 8m, the answer is 22m !
Radius: 3/2 = 1.5m
The perimeter of a triangle is the sum of its three sides. If two are 3m and 2m then their sum is 3m + 2m = 5m And the remaining side can be calculated by taking this sum from the perimeter → the other side is 9m - 5m = 4m long.

If you put an ant down on the rectangle and start him walking along the line, the 'perimeter' is the distance he has to walk in order to get back to where he started, if he stays on the line. If you put him down on a corner of this one, he has to walk (8m + 3m + 8m + 3m) = 22m. That's the perimeter.
1.5m
Isn't it the sum of all sides? 8m+8m+3m+3m = 22m
The perimeter of a rectangle is calculated by adding up the lengths of all its sides. In this case, the rectangle has two sides that are 6 meters long and two sides that are 3 meters long. Therefore, the perimeter would be 6m + 6m + 3m + 3m = 18 meters.
P = 33m + 33m + 3m + 3m = 69 meters
16 metres.
