Can rectangles with the same perimeter have different areas?
Yes. Say there are two rectangles, both with perimeter of 20. One of the rectangles is a 2 by 8 rectangle. The area of this rectangle is 2 x 8 which is 16. The other rectangle is a 4 by 6 rectangle. It has an area of 4 x 6 which is 24.
A group of sudents are finding the perimeters of rectangles whose lengths and widths are whole numbers they notice that all the perimeters are not even numbers is this always true?
No, take the rectangle that is 4x6. The perimeter is 20 which is even.
What rectangles can be with a perimeter of 20 units?
1 x 9 2 x 8 3 x 7 4 x 6 5 x 5 (a square is a rectangle)
What is the area of a perimeter of 20 centimeters?
The perimeter and area don't depend on each other. Knowing one doesn't tell you the other. -- A circle with perimeter (circumference) of 20 cm has area of 31.83 cm2. -- A square with perimeter of 20 cm has area of 25 cm2 . -- A (9 x 1) rectangle has perimeter of 20 cm and area of 9 cm2 . -- A (8 x 2) rectangle has perimeter of 20 cm and area of 16 cm2 . -- A (7 x 3) rectangle has perimeter of 20 cm and area of 21 cm2 . -- A (6 x 4) rectangle has perimeter of 20 cm and area of 24 cm2 .
What is the area of 20 cm2 and the perimeter of 18 cm?
Oh, isn't that just a happy little question? To find the area of a shape, we look at how much space it covers. And to find the perimeter, we add up all the sides. So, for a shape with an area of 20 cm² and a perimeter of 18 cm, we would need more information about the shape to calculate those values. But don't worry, we can paint a beautiful picture with math once we have all the details!
What are some sketches of rectangles with a perimeter of 120?
10 by 50, 15 by 45, 20 by 40.
What are the 5 20 cm rectangles in perimeter?
2*(5 + 20) cm = 2*25 cm = 50 cm.
Can rectangles with the same perimeter have different areas?
Yes. Say there are two rectangles, both with perimeter of 20. One of the rectangles is a 2 by 8 rectangle. The area of this rectangle is 2 x 8 which is 16. The other rectangle is a 4 by 6 rectangle. It has an area of 4 x 6 which is 24.
Are all rectangles with the perimiter of 20 feet equal the same area?
No. For example, a 1 ft by 9 ft rectangle (2 sides of length 1 and 2 sides of length 9) has perimeter 20 ft and an area of 9 square feet. But a 4 ft by 6 ft rectangle also has a perimeter of 20 feet, but an area of 24 square feet. These two rectangles both have the same perimeter of 20 feet but different areas.
How many different rectangles can be made with 20 squares?

What is the perimeter for a polygon that's area is 20sq. units?
Even if you knew how many sides the polygon has, you stillcould not calculate its perimeter with that much information.Examples:-- An equilateral triangle with area of 20 has perimeter of 20.3885 .-- A square with area of 20 has perimeter of 17.889(rounded).-- A rectangle with area of 20 can have any perimeter more than 17.889 .4 by 5 . . . . area = 20, perimeter = 182 by 10 . . . area = 20, perimeter = 241 by 20 . . . area = 20, perimeter = 42..etc.
How much fence is needed to go around a yard?
Dimenisions are required to find the perimeter. And if the perimeter is 20 meters, then you need 20 meters of fence.
A rectangle has a perimeter of 72m If the length is 20 m longer than the width find its dimensions?
a rectangle has a perimeter of 72m. If the length is 20 m longer than the width find its dimensions?
Can 2 rectangles have the same perimeter but different areas?
Of course. A rectangle that is 5 by 5 (yes, that's a square, but a square is a rectangle) has a perimeter of 5 + 5 + 5 + 5 = 20 and an area of 5 x 5 = 25. A rectangle that is 9 by 1 also has a perimeter of 20 (= 9 + 1 + 9 + 1) but an area of 9 (= 9 x 1).
What is the area of a rectangle with a perimeter of 42cm?
You can't tell the area from knowing the perimeter. There are an infinite number of different rectangles, all with the same perimeter, that all have different areas. Here are a few rectangles that all have perimeters of 42. The last number after each one is its area: 1 cm by 20 cm . . . . . 20 square centimeters 2 x 19 . . . . . 38 3 x 18 . . . . . 54 4 x 17 . . . . . 68 5 x 16 . . . . . 80 10 x 11 . . . 110
How many units are there in 20 perimeter?
The question cannot be answered because it makes no sense. The perimeter - of a shape - is the outline of the shape. The is no unit in 20 outlines. Unless you count an outline as a unit and in that case, there are 20.
