No, it is always false. Perimeter of a rectangle= 2l + 2w, l= length, w=width. 2*any whole number, regardless odd or even, is even. Thus 2l is even and 2w is even. The sum of two even numbers is always even.

No, take the rectangle that is 4x6. The perimeter is 20 which is even.

Do rectangles have all equal lengths?

No but they do have 4 equal corner angles of 90 degrees


Why are rectangles squares?

Rectangles are not squares. The reason to this is because squares must have sides of equal lengths. Rectangles are quadrilaterals with sides that join to make 90 degree angles, but are not restricted to having the same length. Therefore "all squares are rectangles", but rectangles cannot be squares.


Ron will use all 900 meters of fence and wants to enclose a rectangular region that contain four congruent rectangular pens within it Calculus optimization i have further questions Please help?

Optimization is all about finding equations that involve your variables, and manipulating those equations to meet the stated constraints. The first step is to find two or more equations involving one or more of your variables. Here, we have cost and two separate lengths. Let's call the long side of each of the small congruent rectangles "l" and the short side "w." You know that you will have four of these rectangles, and because of the situation and the units you know that you will be measuring perimeter. Therefore, the sum of the perimeters of all four congruent rectangles is 4(2l+2w) or 8l+8w. I'm unclear from your question whether Ron will be using the 900 meters to form the four rectangles, or to form the rectangles and to surround them with fencing. Can you give me more information?


Information about a rectangle?

There are plenty of information you can learn about rectangles. You can learn about their angles, their widths and lengths, as well as their volumes.


Are all rectangles the same?

What makes a rectangle and a squarea llike and what makes them different?

Rectangles and squares are alike in that both pairs of their opposite sides are parallel and their inner corners are all 90-degree angles; they are different in that squares have equal lengths on all sides, and only rectangles' opposite sides are the same lengths.


How many perimeters is in 2 inch?

A perimeter is not a unit of length and so the question makes no sense. It is like asking how many lengths in 2 inches.


How many rectangles have the same area but different perimeters?

Infinitely many. Suppose the area of the rectangle is 100. We could create rectangles of different areas: 100x1 50x2 25x4 20x5 10x10 However, the side lengths need not be integers, which is why we can create infinitely many rectangles. Generally, if A is the area of the rectangle, and L, L/A are its dimensions, then the amount 2(L + (L/A)) can range from a given amount (min. occurs at L = sqrt(A), perimeter = 4sqrt(A)) to infinity.


What lengths do you use when finding area of parallelogram?

Square metre


How do you work out the area of an L shape?

You should break it down in to smaller shapes. Two rectangles. Then figure out all the lengths. Multiply to find the area of the two rectangles. then add the products to get the final area.


Finding areas of oddly shaped rectangles?

What is an "oddly shaped rectangle"? Rectangles have four sides, with two pairs of sides that are equal in length and parallel to each other, and four right angles. Anything that fits this definition is a rectangle, period. There's nothing "odd" about any of them. But the area of any rectangle can be found by multiplying the lengths of any two adjacent sides.
