What is a perimeter of a rectangle?
That depends. The perimeter of a rectangle equals the all the sides added together! The perimeter of a rectangle is the distance around it. The formula for finding the perimeter of a rectangle is: P = 2L + 2W (the length x 2 added to the width x 2). Example: A 5x10 rectangle has a perimeter of 30: (5x2 + 10x2 = 30)
If a rectangle has a width of 3r and a length of 5 plus 7r what is its perimeter?
20r + 10
What happens to the perimeter of a rectangle when you double one of its dimensions?
The perimeter of a rectangle is given by (2L plus 2W). If you double either the width or length dimension, then it is four times the original dimension, such as (4L plus 2W) or (2L plus 4W).
The width of a rectangle is X plus 4Cm its length is X plus 7Cm greater than its width represent its perimeter and simplify?
width = (x + 4) cm length = [(x + 4) + (x + 7)] cm Rectangle Perimeter = 2[(x + 4) + (x + 4 + x + 7)] cm Rectangle Perimeter = 2[(x + x + x) + (4 + 4 + 7)] cm Rectangle Perimeter = 2(3x + 15) cm Rectangle Perimeter = (6x + 30) cm
If a rectangle has 50 inches what is its length and width?
If "50 inches" is the perimeter all you can say is that length plus width = 25 inches.
What is length plus width?
2 times length plus 2 times width = perimeterhalf the perimeter of a rectangle

How do you get a perimeter of a rectangle?
Add up (double the length) plus (double the width).
What is the area and perimeter of a shaded rectangle?
The area is the length times the width. The perimeter is two times the length plus two times the width.
If a rectangle has a width of 3r and a length of 5 plus 7r what is its perimeter?
20r + 10
How do i find the perimeter of a rectangle if you know its length and its width?
Add up (two lengths) plus (two widths) and you have the perimeter.
What is the perimeter of a rectangle with length 42 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.
What happens to the perimeter of a rectangle when you double one of its dimensions?
The perimeter of a rectangle is given by (2L plus 2W). If you double either the width or length dimension, then it is four times the original dimension, such as (4L plus 2W) or (2L plus 4W).
The width of a rectangle is X plus 4Cm its length is X plus 7Cm greater than its width represent its perimeter and simplify?
width = (x + 4) cm length = [(x + 4) + (x + 7)] cm Rectangle Perimeter = 2[(x + 4) + (x + 4 + x + 7)] cm Rectangle Perimeter = 2[(x + x + x) + (4 + 4 + 7)] cm Rectangle Perimeter = 2(3x + 15) cm Rectangle Perimeter = (6x + 30) cm
If a rectangle has 50 inches what is its length and width?
If "50 inches" is the perimeter all you can say is that length plus width = 25 inches.
Is the perimeter of a rectangle twice the width plus twice the length?
yes, because in finding perimeter youre just adding all of the sides together.
Show a rectangle that has permeter and area?
The area is the length times the width. The perimeter is two times the length plus two times the width.
