If the only known fact is the length of the diagonal then the width and length of the rectangle CANNOT be determined. The diagonal could be that of a square, or of a rectangle that is very long but quite narrow. Consequently at least one more fact is required such as; the dimension of either the length or the width, or the angle that the diagonal makes to the base of the rectangle or even the area of the rectangle.
Use Pythagoras' theorem
the length of a rectangle is 8 more than the width. the area os 345 centimeters. find the length and width of the rectangle
For a rectangle or square, Area = Length * Width So Length = Area / Width.
Area of rectangle divided by its length = width of rectangle
you need length and width length multiply width = area length + length + width + width = perimeter

First, you must find the width. Use Pythagoras' Theorem. Then, just add the lengths of the four sides, to get the perimeter.
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
For a rectangle, area equals length times width. To find the length given the width and area, divide the area by the width.
the length of a rectangle is 5 more then the width. Find the perimeter and the area of the rectangle
For a rectangle or square, Area = Length * Width So Length = Area / Width.
length times width
Area of rectangle divided by its length = width of rectangle
Multiply the length and width to find the area of both a rectangle and square.
you need length and width length multiply width = area length + length + width + width = perimeter
Divide the width by the length: width -------- height
