If you don't know the width, area or length, you would have to have several other measurements that would permit you to calculate the width or length.
A rectangle's main formula is l x w x h (length times width x height). If you don't have two of them, finding the third one is complicated, but doable under some select circumstances.
If you had the lengths of two sides of a triangle with two vertices matching two of the rectangle's vertices, you could use trigonometry find the length of the shared side. If this shared side was the length then you would be golden.
Or you could measure.
Length times width.
Area of rectangle is l x b. Where l is length and b is breath of the rectangle.
Length x Width LxW
length times width
I beleve that is the formula for finding the area of a rectangle or squareLength*Width equals area for rectangles. LxW=Area of a rectangle.
Knowing the length and the width.
Sorry, without knowing the length it could be anything !
A = lw Area of a rectangle = length times width
Length times width.
Area of rectangle is l x b. Where l is length and b is breath of the rectangle.
Length x Width LxW
length times width
With X length = square
in finding the area if a square or rectangle multiply the length and width, for a triangle, multiply length and width divided by two.
With Pythagoras' theorem: diagonal2- length2 = width2
length X width, assuming that it is a perfect rectangle.
the area of a triangle is base times height times one half and rectangle is length times width
