Answer depends on what the shape is and what other information is available.
Lenght X width = surface area
It is length * width.
Surface area = length*width in square units
To find the area, multiply the height by the width.
Hight X Width
That will depend on the information given as for example if you are given its width and area then in order to find its length divide the width into the area.
Length X Width.
divide surface area by width Sorry It is a little more complicated than that. Surface area = (2 X length X width) + (2 X length X height) + (2 X width X height) Solve for height Surface area - (2 X length X width) = 2height(length + width) (Surface area - (2 X length X width))/2(length + width) = height
You usually find the area by length*width, that is how I was taught.
You cannot.
To get the surface area, someone had to multiply length times width. So what we would need to do is take our surface area, divide by our height, which is our width, and get our length. So if SA stood for surface area, and h stood for height, we'd take SA/h to get the length.
Area is a plane or surface measurement. Depth is not required. Multiply the length by the width.
