Find the width, and multiply the length and the width.
Nearly always multiply. However, for the perimeter of a rectangle, you add the length + width + length + width. This is even simplified by multiplying the length and the width by 2
Multiply the length and width to find the area of both a rectangle and square.
To find the length of a triangle or what ever shape your trying to find all you have to do is multiply width times the area. * * * * * Or, if you want the correct answer, you could try to divide the area by the width. That assumes the shape is a rectangle and that the area and width are known!
Yes, the area of an object is most commonly width times length.
multiply length and width
multiply length times height times width
You multiply the length and width to get the volume
to find area you multiply length times width to find volume you multiply length times width times heights
You find its area.
length*width = 2*width*width i.e square the width and multiply by 2
multiply the length and the width
