Let its length be 4x and its width be x:-
So: 4x times x = 30976 sq cm => 4x squared = 30976 sq cm
Then: x = square root of 30976/4 => 88
Perimeter: (4*88)+(4*88)+88+88 = 880 cm
Check: (4*88)*88 = 30976 sq cm

What is the perimeter of a square that has an area of 81 meters square?
36, area is equal to length X width, perimeter is equal to 2(length)+2(width) in a square length is equal to width, so we take the square root of the area to find that both are 9, which means the perimeter is 9 X 4, 36.
What is the greatest area possible for garden if it is to be rectangular have a perimeter of 38ft and each edge is to be a measurement in whole ft?
I get 90 square feet as follows. The perimeter is equal to twice the sum of the length and the width. P 2(L+W) so that the length plus the width is 19 ft. The combination of all pairs of integers that sum to 19 have products equal to or less than 9X10 90.
Given the perimeter of a square how can the length of each side be determined?
In general, the perimeter of a polygon is equal to the sum of the length of its sides. If a square has sides of length s, it's perimeter is equal to s + s + s + s. In other words, P = 4s. Rearranging this equation we get s = P/4, so the length of any side of a square is equal to one fourth of the square's perimeter. For example, if the perimeter is 32, the equation becomes s = 32/4 32 divided by 4 equals = 8 so if the perimeter of a square is 32, it has sides of length 8.
If two sides of an octagon with equal sides is 24 cm what is the perimeter?
we make the assumption that all sides are equal length, that is to say it is a regular octagon. Then one side has length 12 if 2 sides have length 23. So the perimeter is 8x12=96 cm
What is the perimeter if the length is 7 and the width is 2?
Assuming the object is shape with opposite sides of equal length then the perimeter would measure 2 * 7 + 2 * 2 =18
What are the rectangles found by the greek that have the same perimeter and length?
No rectangle can have equal perimeter and length.
The perimeter of the square and then convert the answer to meters?
The perimeter of a square is four times the length of a side - since the square has 4 sides of equal length.The perimeter of a square is four times the length of a side - since the square has 4 sides of equal length.The perimeter of a square is four times the length of a side - since the square has 4 sides of equal length.The perimeter of a square is four times the length of a side - since the square has 4 sides of equal length.
What is the perimeter of a heptagon?
A heptagon is a shape that has seven sides of equal length. The perimeter of a heptagon can be found by multiplying the length of one side by seven. * * * * * No! The perimeter is the sum of the lengths of the seven sides. There is absolutely no requirement for the seven sides to be of equal length!
What is the perimeter of the largest rectangular in circle?
The largest diameter you can inscribe in a circle is a square. The square's diagonal is equal to the diameter of the circle; the length of the side of the square is therefore equal to the circle's diameter, divided by the square root of 2.
What makes the cube and the rectangular prism different?
Cube all sides equal length,: rectangular prism opposite side equal
The perimeter of an equilateral figure can be found by multiplying the number of sides by the length of one side?
This is true. A square, which has four equal sides, will have a perimeter equal to four times the length of a single side.An equilateral triangle, which has three equal sides, will have a perimeter equal to three times the length of a single side.Any regular polygon contains all sides of the same length, therefore, the perimeter of a shape with a certain number of sides will be equal to the length of one side multiplied by the number of sides.
A rectangular solid that have equal length width height?
cube
How does perimeter relate to area?
The perimeter is equal to length + length + width + width while area is length x width. Both measurements are found by using width and length.
What are the differences between a rectangular prism and a cube?
A cube is a rectangular prism where all sides are of equal length.
The length of a rectangle is equal to three times its width if the perimeter is equal to 40 feet what is the length of the rectangle?
15 feet.
The length of a rectangle is equal to three times its width if the perimeter is equal to 168 feet what is the length of the rectangle?
63 feet
What is an expression for the perimeter of a rectangle that has a length which is seven times its width?
Perimeter = length + length + width + width Let "w" = width, then "7w" must equal the length (because it's 7 times the width) 7w + 7w + w + w = perimeter 16w = perimeter
