easy!
5x+4y=18, and 2x+y=6, and we know that the long side is 3 times longer than the short side (6 times 3 is 18), so
3(2x+y)=5x+4y
so, 6x+3y=5x+4y
so, x+3y=4y
so, x=y
so, we now know that x=y.
you then change the first equation to:
5x + 4x = 18 (because both long sides of a rectangle are equal)
so, 9x = 18, and x=2. And that means y also = 2.
If you increase the rectangle's length by a value, its perimeter increases by twice that value. If you increase the rectangle's width by a value, its perimeter increases by twice that value. (A rectangle is defined by its length and width, and opposite sides of a rectangle are the same length. The lines always meet at their endpoints at 90° angles.)
Possibly. The perimeter of a rectangle is the distance around the outside of the rectangle. A rectangle has four sides with opposite sides being congruent. The formula for finding the perimeter is Side A + Side B + Side A + Side B-Devon
Assuming x is one of the sides of he rectangle, any value greater than zero and less than 71/2.
This would be a square, not a rectangle. In either case to get square value just multiply length times width.
A rectangle has no value - experimental or otherwise. Its area has a value, its perimeter, its aspect have values.

It is false. The first part about the square is true, but the second part is false. A rectangle has two pairs of parallel sides. The "and' means that both parts must be true for the statement to be true. A convex polygon can have many pairs of parallel sides, but you can never have 3 or more sides all parallel to each other.
This would be a square, not a rectangle. In either case to get square value just multiply length times width.
The perimeter of a rectangle is just the sum of the lengths of its sides, so taking half of each of the sides would make the total half of its original value also.
Since the largest area would be obtained by having adjacent sides equal to each other, and since a square is at least technically an equilateral rectangle, divide the perimeter of 72 by 4 to get sides of 18 and an area of 324.
A rectangle has no value - experimental or otherwise. Its area has a value, its perimeter, its aspect have values.
What is the length of the rectangle? If you had said one of the sides of a square was 3 inches, you could multiply 3 inches by 3 inches to get the value in square inches.Area = 3l square inches, where l = length of the rectangle in inches.
If you are given two similar rectangles, one with all measurements and the other with only one, you first need to find the conversion ratio. Let's call the rectangle that you know everything about, rectangle A, and the other rectangle B. You take the ratio of the side of rectangle B to rectangle A. You then multiply the length of rectangle A by this value, to find the length of rectangle B.
length is 4x and width is x: 4x*x = 80 4x2 = 80 Divide both sides by 4: x2 = 20 Square root both sides: x = 4.472135955
Any number less than 576 cm2. A square, with sides of 24 cm will have a perimeter of 96 cm and an area of 576 cm2. Suppose the sides of the rectangle are 24+x cm and 24-x cm, where 0<x<24. Then the perimeter will be 96 cm while the area will be (24+x)*(24-x) = 576 - x2 cm2 The area can have any value in the range (0, 576) depending on the value of x.
