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 !

22 meters The perimeter (distance around the outside) = length + width + length + width P = 2L + 2W 2 (8) + 2 (3) = 16 + 6 = 22 also: P = 2 (L + W) 2(8 + 3) = 22

16 metres.

P = 33m + 33m + 3m + 3m = 69 meters

Since the formula for the perimeter of a rectangle is 2 times the lenght plus 2 times the width (P = 2l + 2w). P = 2(8) + 2(3) P = 16 + 6 P = 22m

Perimeter = 33+33+3+3 = 72 m

Sum of the sides ie 8+8+3+3 = 22m. p=2l+2w thus, p=2(8m)+2(3m) p=16m+6m p=22m so the perimeter is 22m. yrevoj.
