So you are looking to find the perimeter of the square.
Since the area of the square is 118.81 m2, then the perimeter is 4(√(118.81 m2) = 43.6 m.
There are 100 square decimetres in one square metre. Therefore, 4 square metres is equal to 4 x 100 = 400 square decimetres.
2400 square meters
22.1 square meters.
Square meters of what? If you want the area in square meters of a rectangle, just multiply the length times the width (both in meters). To get square meters of other figures, other formulae are required.
186.6 square yards of carpet are needed.
100 square meters
That is called "square decimeters" and "square meters". Since one meter has 10 decimeters, one square meter has 10 x 10 = 100 square decimeters.
30.66 sq meters You just multiply the two values.
These questions are asking you to calculate the perimeter, which is the total length of all sides. For the first field, you can calculate the answer by calculating the square root of the area (for 118 = 10.86), which gives the length of each side. Since they are all equal on a square, multiplying this value by 4 will give the perimeter: 43.45 m. For the second, the calculations work the same way. If working with decimeters is nerve-wracking you could convert to meters by multiplying by 10, but remember that your answer would be in meters. The square root of 81 is 9. 9 x 4 = 36 decimeters.
I suppose you mean square decimeters. Since a meter has 10 decimeters, a square meter has 100 square decimeters.
ten decimeters
6270.955 square decimeters
You can't convert between square meters and cubic meters.
There are 100 square decimetres in one square metre. Therefore, 4 square metres is equal to 4 x 100 = 400 square decimetres.
2400 square meters
22.1 square meters.
The perimeter of a square is four times the length of one side. If each side is 10m, 40m of fencing would be required to enclose a pasture, less whatever is required for the gate.
