6 units.
Given the length of the diagonal of the square ... call it 'D units'. The area of the square is (1/2 D2) (same units)2.
For a square, the length of each side is equal to the square root of the area. In this case, the square root of 36 is 6. So, each side measures six units.
If the only information that you have is ... A) the figure is a rectangle, and B) the perimeter ... then you cannot calculate the area. The area of a rectangle is the length multiplied by the height., The perimeter is twice the length plus twice the height. So, a rectangle with a length of 9 units and a height of 1 unit will have a perimeter of 20 units and an area of 9 square units. Another rectangle with a length of 6 units and a height of 4 units will also have a perimeter of 20 units, but it will have an area of 24 square units. To be able to calculate the area from the perimeter you need to know one of two additional things - either one of the measurements, or the ratio of the height to the length.+++To summarise, you can, IF you know the ratio as mentioned. Then apply that to half the perimeter to find the length and breadth.
Take the square root of the area.
Volume = Length*Area of cross-section So area of cross section = 1962.5/25 = 78.5 units If the cylinder has diameter d then area of cross section = pi*d2/4 So d2 = 4*Area/pi = 99.95 square units. Then d = sqrt(99.95) = 9.997 units of length.
Each side of the square is 4 units in length
Area in square units = length*width
Given the length of the diagonal of the square ... call it 'D units'. The area of the square is (1/2 D2) (same units)2.
Surface area = length*width in square units
Area of a parallelogram in square units = length*perpendicular height
0.0625 square units
Multiply LxW. The units must be the same. This will give you the area in square units.
If the side length is s units then the area is s2 square units. So, given the area, take the principal square root.
Length times width equals your units 2
area = length by length. 3 x 3 = 9 units squared
To find the area of a region for which you have the length and width, simply multiply the length by the width. Thus, for a room 13 units by 9 units, the area is 13 x 9 = 117 square units.
For a square, the length of each side is equal to the square root of the area. In this case, the square root of 36 is 6. So, each side measures six units.
