1. ok you have four coordinates
2. chart your coordinates on a grid (these should make a square when you connect them in order)
3. count the units between the points
To find the length of a side, you either measure it, or you calculate it. How you calculate it depends on what data is given. For example, if you have the coordinates of the endpoints of a line, you can calculate the length by using the Pythagorean theorem (or simply subtracting the coordinates of the two endpoints, if the line is perfectly vertical or perfectly horizontal).
That would depend on the length of the rectangle which has not been given but the area of a rectangle is length times width
You cannot.
Divide the area by the width and it will give you the length.
by appying 2l+2w
Divide the area by the length of the rectangle

the area of a rectangle = length x widthwe can rearrange this to give uslength of a rectangle = area/ width
If a rectangle has its length equal to its width, then all four sides are of equal length and it is a square.
56 cm Perimeter of a rectangle is given by 2(length + breadth). So, perimeter of given rectangle = 2(18 + 10) = 56
you divide the area by the length and you have the other side
Given what? Probably measure it
The length and width can't be determined since it is a rectangle. A length would need to be given, or it would have to be a square.
The rectangle has a length of 12.
Divide area by length and that gives you width.
