Length of rectangle is 5 inches and its width is 4 inches Check: 2*(5+4) = 18 inches which is its perimeter

Length + width = half perimeter = 100". Length is 98", width is 2"

The perimeter of a rectangle = 2 x (length + width) = 2 x (12 + 8) = 2 x 20 = 40 inches

A rectangle has two dimensions, length and width. You haven't said what the width is. The perimeter is the distance around the rectangle. Imagine going round it. You would go 42 inches, then a width, then another 42 inches, then another width. In general, the perimeter of a rectangle is twice its length plus twice its width.

If the length of a rectangle is twice its width and it has a perimeter of 48, then the rectangle is 16 in length and 8 in width.

Its length is 18 inches

Perimeter = length + width + length + width = 2 x (length + width) Given: perimeter = 22in length = width + 3in Thus 22 = 2 x (width + 3 + width) 11 = 2 x width + 3 8 = 2 x width 4 = width So the width is 4in.

If "50 inches" is the perimeter all you can say is that length plus width = 25 inches.

Do-it-in-your-head method: Length + width is half the perimeter which is 27 inches; 27 minus 6 is 21 and one-third of 21 is 7 which is the width. (Length = 2 x 7 + 6 = 20)

20

28 inches

10 inches

22 inches

perimeter 24 so length + width half of that ie 12. Length 3 times width must be 9 and width 3.

Perimeter is Length + width x 2 or Length + length + width + width. This is perimeter for any shape including a rectangle. Perimeter of a rectangle is all sides added together for a rectangle.

I think its 18

82 inches.

Width = 9 inches Length = 30 inches

Length + width = half of perimeter ie 36.7 in. If length is 4.7 in then width is 32 in.

Perimeter = 11+11+8+8 = 38 inches

length + width = 1/2 x 60 in = 30 inches The length is 3 inches more than than the width, so length is 16.5 inches and width is 13.5 inches.

Perimeter = 2*(Length + Width) = 2*(16 + 12) = 2*28 = 56 inches

17 inches.
