A rectangle whose opposite sides are 4 cm and 2.5 cm. Its perimeter is 2*(4 + 2.5) = 2*6.5) = 13 cm.

Is The area of a rectangle always greater than the perimeter?

No,for example, a 1x2 rectangle has an area of 2 but a perimeter of 6

In general describe the rectangle that has the least area for a fixed perimeter?

For a fixed perimeter, the area will always be the same, regardless of how you describe the rectangle.

Why is the perimeter of rectangle with an even width and lenght always an even number?

If both numbers are even, it will always be an even number. For example, 2 + 2 = 4.

Is the perimeter of a rectangle always greater than its area?

To answer this simply try a few out for yourself. In a 2x1 cm rectangle, the area is 2 cm squared and the perimeter is 6 cm In a 12x10 rectangle, the area is 120 cm squared and the perimeter is 44 cm. In some cases, the perimeter is larger and in others it is smaller. To answer your question, no, the perimeter of a rectangle is NOT always greater than its area.

Why is the perimeter of a rectangle always even?

The perimeter of a rectangle is always even because the perimeter is twice the length plus twice the width. Whenever you multiply a number by 2, the product is even. When you add two even numbers the sum is even.

Does changing the area always change the perimeter?

No. A rectangle of 1 x 3 has the same perimeter as a rectangle of 2 x 2, but the areas are different.

A parallelogram is always an example of?

a parallelogram is always a example of a rectangle a rhombuz and a trapezoid

What is a rectangle always an example of?

A rectangle is always a quadrilateral and a parallelogram.

How does increasing the dimensions of a rectangle impact the perimeter?

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.)

Can a rectangle have the same perimeter but different area explain?

No, any shape with four sides and same perimeter will always be a square.

What is area and perimeter?

Area is length times width (only for rectangle) while perimeter is all the sides added up (always).

If two rectangle have the same area must they have the same perimeter?

Not always because a 2 by 12 rectangle will have the same area as a 4 by 6 rectangle but they both will have different perimeters.

Are two rectangles with the same perimeter always congruent to each other?

no because one rectangle may be 3x4 which the perimeter is 14 and one rectangle may be 5x2 which as well equals 14

A rectangle had an area of 24ft2 what is the length and width of the rectangle with the greatest perimeter?

The rectangle with the smallest perimeter for a given area is the square. The rectangle with the greatestperimeter for a given area can't be specified. The longer and skinnier you make the rectangle, the greater its perimeter will become. No matter how great a perimeter you use to enclose 24 ft2, I can always specify a longer perimeter. Let me point you in that direction with a few examples: 6 ft x 4 ft = 24 ft2, perimeter = 20 ft 8 ft x 3 ft = 24 ft2, perimeter = 22 ft 12 ft x 2 ft = 24 ft2, perimeter = 28 ft 24 ft x 1 ft = 24 ft2, perimeter = 50 ft 48 ft x 6 inches = 24 ft2, perimeter = 97 ft 96 ft x 3 inches = 24 ft2, perimeter = 192.5 ft 288 ft x 1 inch = 24 ft2, perimeter = 576ft 2inches No matter how great a perimeter you find to enclose 24 ft2, I can always specify a rectangle with the same area and a longer perimeter.

Is it sometimes always or never true that the perimeter of a rectangle is numerically greater than its area?

Sometimes. Experiment with a small square and with a large square (though any shape rectangle will do). A square of 4 x 4 has a perimeter of 16, and an area of 16. A smaller square has more perimeter than area. A larger square has more area than perimeter.

A rectangle is always an example of a?

A quadrilateral shape

How does the length and width of a rectangle relate to the perimeter?

If you add the length and width together, it will always be half of the perimeter. In terms of an equation, it would look like so: Perimeter = (2 x Length) + (2 x Width)

when you are trying to find the area or perimeter of something do you multipli?

Nearly always multiply. However, for the perimeter of a rectangle, you add the length + width + length + width. This is even simplified by multiplying the length and the width by 2

A square is always an example of what?

A quadrilateral, a parallelogram, a rhombus, a rectangle, a regular polygon.

What is the maximum area of a rectangle with a perimeter of 130?

130/4 (4 sides to a rectangle)= 32.5 32.5*32.5=1065.25 square meters (because the largest area of a rectangle is always a ^ ^ square). length width

Rectangle whose perimeter is larger than area?

Perimeter is a unit of length. Area is a unit of area. The two units are not directly convertible.However, the area of a rectangle is length times width, and the perimeter is two times length plus two times width. Given constant perimeter, a square has maximum area, while a very thin rectangle has nearly zero area. (In calculus terms, the limit of the area as length or width goes to zero is zero.)Depending on how you want to name your units, you can always find a rectangle whose perimeter is "larger" than area, but this is a numerical trick that is not valid in any school of thought of mathematics that I know.

If the perimeter is 1213 cm find the length of each side?

All we can tell is length plus width is 606.5 ...(always assuming you're talking about a rectangle)

What is the largest possible perimeter area 49cm squared in rectangle?

It can be infinitely large. Consider a rectangle of length A cm where A ≥ 7 cm. And let its width be B = 49/A cm. Then its area is always A*B cm2 = A*49/A cm2 = 49 cm2. Let A = 10 cm, B = 4.9 cm so perimeter = 29.8 cm or A = 100 cm, B = 0.49 cm, perimeter = 200.98 cm or A = 1000 cm, B = 0.049 cm, perimeter = 2000.98 cm By making the rectangle infinitesimally thin and infinitely long, its perimeter can be increased without limit.
