The length of a rectangle is 3 units greater than its width. Which expression would correctly represent the perimeter of the rectangle? 2W+ 2W+3) W+W+3 w(w+3) 2W+2(3W)
10. A rectangle has a length that is 3 cm longer than its width. If x represents the width of the rectangle, which expression represents the perimeter of the rectangle? a. 4x + 3 b. 4x + 6 c. 2x + 3 d. 2x + 6
please answer all C. 2. What rectangle has the smallest perimeter, for a given area? Suppose you want a rectangle with area 200. What choice of length L and width W will give the smallest perimeter? a. Sketch a rectangle and label it as having length L and width W. b. Write the area in terms of length and width: A = Write the perimeter in terms of length and width: P = d. If L = 200 and W...
You may remember that the perimeter of a rectangle is P=2(W+L) where W is the width and L is the length. Suppose that the perimeter of a rectangle is 44 feet, and the length is 12 feet more than the width. Find the width of the rectangle, in feet.
The length of a rectangle is 3 yd more than twice the width x. The area is 495 yd. Find the perimeter P of the rectangle. P-48 yds P-96 yds P. 192 yds P-33 yds
In the code (C++) below, if you input 2 as length and 4 as width, the output is: Enter the rectangle's length: 2 Enter the rectangle's width: 4 Length: 2 | Width: 4 | Area: 8 | Perimeter:12 We worked on this code during class, but there were some things that I did not understand. 1) how does compiler read"l" as length, "w" as width, etc.? I thought you had to update it first, like "w=width." 2) i thought you...
write a program in c ++ that reads the length and width of a rectangle from a file named input.txt and write the area and perimeter of the rectactangle to file named output.txt
The length of a rectangle is 12 more than its width. The ratio of length to width is 11 to 8. Find the dimensions of the rectangle.
Construct a C++ class named Rectangle that has floating-point data members named length and width. The class should have a zero-argument constructor that initializes each data member to 0. It should have member functions named calcPerimeter() and calcArea() that calculate the perimeter and area of a rectangle respectively, a member function setLength() and setWidth() to set the length and width, member functions getLength() and getWidth() to return the length and width, and a member function showData() that displays the rectangle’s length,...
Create a class Rectangle with attributes length and width, each of which defaults to 1. Provide methods that calculate the rectangle's perimeter and area. It hasset and get methods for both lengthand width. Theset methodsshould verify that lengthand width are each floating-point numbers larger than 0.0 and less than 20.0. Write a program totest class Rectangle.Program should be written in Java .I need some with this problem so urgently----test is due tomorrow and will be similar tothe above question. I...
