If a rectangle is 3 more than 7 times the width and the perimeter is 54 what is the dimension of the rectangle?
(1) L = 7W + 3
(2) 2L + 2W = 54
Substituting (1) in (2) ...
2(7W+3) + 2W = 54
14W + 6 + 2W = 54
16W = 48
W = 3
L = 7x3 + 3 = 24
So, length is 24 and width is 3

What is the area of a rectangle that its perimeter is 39?
156 It is impossible to calculate the area of a rectangle from its perimeter if no other dimension is known. The area of a rectangle is the product of its length and width, and the perimeter is twice the sum of its length and 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).
What is the effect on the perimeter of a rectangle if the dimension are doubled what is the effect on its perimeter?
A rectangle has two dimensions - length and width. Only if both dimensions are doubled, then the perimeter will be doubled.
Perimeter of a rectangle?
2 times (length + 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.
What is the perimeter of a rectangle whose dimension are the length is 24.6 the width is 12.2?
Perimeter = 2*(Length + Width) = 2*(24.6 + 12.2) = 2*36.8 = 73.6 units
What is the width of a rectangle with a perimeter of 34 cm and a length of 15 cm?
Its width would be 2cm. To find the missing dimension, divide the perimeter by two, then subtract the known variable.
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 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.
