The side-lengths of a 4-sides figure is not enough information to determine its area.
Consider a square which can be flexed into a rhombus and that rhombus can be made very very flat so that its area is almost zero. In a similar way, all quadrilaterals are non-rigid. They can be flexed so that their area changes without altering the side-lengths.
The Area Of A Shape Is Multiplying The width * The Length
you times the width by the length of the shape
24 area= length multiplied by width
Area = length * width
A long tape measure helps. To find the area: length times width. If it's an irregular shape, then you might want to quadrant it off and measure the irregular parts separately.
You times the length by width, to get the area of the 2D shape.
Multiply length multipled by the width
length times width
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!
Area of a rectangle is length times width.
A regular shape such as a square or rectangle - length times width. If it is an irregular shape, fit known sized squares and triangles within the shape's border and work out area of a square and a triangle times the number of squares and triangles.
you times the width by the legnth of the shape
