What are all possible rectangles with a perimeter of 26 cm and whole number lenthes of sides?
5
What is the area of a square with a perimeter of 20 centimeters?
The area of square is : 400.0
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).
How could you find the perimeter of a square with sides 5 cm without drawing a picture?
No picture is required because a square has four equal sides, so each side is 5 cm long. Perimeter is the measure around the outside of the figure, so you simply add 5+5+5+5 or multiply 5x4 to get 20 cm. Easy peasy. :)
Why is the perimeter of a square greater than the perimeter of a rectangle?
It is not. The perimeter of a 1 cm square is 4 cm. The perimeter of a 5 km * 15 km rectangle is 4000000 cm: a million times as large!

What is the perimeter of a square with sides of 5 cm?
20 cm !
What is the area of a square with a perimeter of 20 centimeters?
The area of square is : 400.0
What is an area of an square with a perimeter of 20 cm?
Each side = 20/4 = 5 cm Area = 5*5 = 25 square cm
What is the area of 20 cm2 and the perimeter of 18 cm?
The area is already shown as 20 cm2 . A rectangle with sides of 4 cm and 5 cm will have an area of 20 cm2 and a perimeter of 18 cm.
What is the length of one side of a regular pentagon if its perimeter is 20 cm?
20 cm/5 = 4 cm
What is the perimeter square whose sides equal 5 centimeters?
Assuming by "equal" you mean that each side is 5 cm, then the perimeter of a square is 5 cm * 4 (sides) = 5 cm + 5 cm + 5 cm + 5 cm = 20 cm The perimeter of any polygon is the sum of the sides Alternatively if by "equal" you mean the sides sum to 5 cm, then the perimeter is 5 cm. Although this is probably not what you meant =)
How do i sketch and label all possible rectangles with a perimeter of 30 cm and sides whose lengths are whole numbers?
5
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
What is the perimeter of a square with an area of 25 cm 2?
Since it is a square, all four sides are the same. The side is sqrt(25 cm2) = 5 cm. The perimeter is 4 x 5 cm = 20 cm.
How many different rectangles can you draw which has a perimeter of 24 cm?
Providing that they are whole numbers: 1*11 , 2*10, 3*9, 4*8, 5*7, 6*6 and 7*5 cm
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).
