The length of a rectangle is 2 cm more than four times the width If the perimeter of the rectangle is 84 cm what are its dimensions?

L + W = P/2 = 42 ie L = 42 - W;
L = 4W + 2 so 42 - W = 4W + 2 ie 5W = 40 so width is 8 cm making length 34 cm

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.
The length of a rectangle is equal to three times its width if the perimeter is equal to 40 feet what is the length of the rectangle?
15 feet.
The perimeter of a rectangle is 24 inches. And its length is 3 times its width. What are the length and the width of the rectangle?
perimeter 24 so length + width half of that ie 12. Length 3 times width must be 9 and width 3.
What is length plus width?
2 times length plus 2 times width = perimeterhalf the perimeter of a rectangle

If the perimeter of a rectangle is twenty four inches find the dimensions if its length is three times the height.?
That would be 3 x 9 inches.
Perimeter of a rectangle?

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).
A rectangle has a length three times its width The perimeter is 64?
twice length + twice width = perimeter In this example, L= 3W 2(3W)+2(W)=64 8W=64 W=6 L =3W L=18 The dimensions of this rectangle are: 18 by 6
How is perimeter and area related in a rectangle?
The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)
The length and width of a triangle are each multiplied by 4 find how the perimeter and the area of the rectangle change?
As written, that's confusing. The length and width of a triangle wouldn't have any bearing on the perimeter and area of a rectangle unless they overlap in some drawing that only you are looking at. Let's assume you meant rectangle all along. If the dimensions of a rectangle increased 4 times the perimeter would also increase 4 times. The area would increase 16 times. Try it out. A 2 x 3 rectangle has perimeter 10 and area 6. An 8 x 12 rectangle has perimeter 40 and area 96.
