Perimeter is just twice the sum of length and width, in this case 2 x 11 m ie 22 m.
Perimeter = 33+33+3+3 = 72 m
Use Pythagoras' theorem:- 82+32 = 73 and the square root of this is length of the diagonal which is about 8.544m to 3 decimal places
That depends on the dimensions !... A 1 x 18 rectangle has a perimeter of 38 ! A 2 x 9 rectangle has a perimeter of 22 ! A 3 x 6 rectangle has a perimeter of 18 !
what is the perimeter of a 11cm x 10cm rectangle answer 42
