The Landscape Fabric Needed for Four Sided Area calculators computes the number of rolls of landscape or garden fabric to cover an area such as a garden or planter.
INSTRUCTIONS: Choose units and enter the following:
- (a) Length of side a
- (b) Length of side b
- (c) Length of side c
- (d) Length of side d
- (D) Length of the diagonal (see diagram)
- (FRW) Width of Fabric Roll
- (FRL) Length of Fabric Roll
Landscape Fabric Needed for an Irregular Area(LSF): The calculator returns the number of standard rolls of landscape fabric and the area of the garden in square feet. However, these can be automatically converted to compatible units via the pull-down menu.
The Math / Science
A four sided area is considered a quadrilateral. The calculator computes the area of the quadrilateral using the length of the four sides and the diagonal. It then computes the number of rolls of garden/landscaping fabric by dividing the area by the area in a standard roll of garden fabric.
Landscape fabric Information
Landscape fabric is a cloth (textile) material used in gardening and landscaping. It's primary purpose it create areas of no plant growth except where the fabric is cut and specific desirable plants are planted. In this way, undesirable plants including weeds are block from growth by being denied sunlight. Since it is a fabric, landscaping fabric is subject to being blown away by wind until something heavy is on it, like decorative stones, or until fixed to the ground using garden staples. Southwest Boulder & Stone (75 and 500 pack) and Vigoro (100 pack) are to manufactures of garden staples.
Landscape fabric comes rolls of various sizes. A recent survey showed the following size options.
