what is the perimeter of a rectangle 8mm by 3m
not good
Hi

(L + W) x 2 (8 + 3) x 2 = 11 x 2 = 22m
A rectangular prism with a length of 11m, width of 8m and height of 3m has a volume of 264m3
Perimeter is just twice the sum of length and width, in this case 2 x 11 m ie 22 m.

Isn't it the sum of all sides? 8m+8m+3m+3m = 22m
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.
Assuming that the measures given in the question refer to the lengths of the sides of the rectangle, the answer is 40 metres.
If you mean an area measuring 3m x 8m, the answer is 22m !
it is the amount of squares.
25mL * 3M / 8M = 9.4 mL

(L + W) x 2 (8 + 3) x 2 = 11 x 2 = 22m
8m*5m=40 m2 The area of the rectangle is 40m2
