If you have a mulch bed that is a strange shape, can you use a waking wheel to measer the perimeter then convert that to a rectangular shape to figure the area? For example, your perimeter of this odd shape bed is say, 58 feet. If you have a rectangle 1' x 28' (which has the same 58' perimiter) that would give you a quick area calculation. Is this right or am I experience a brain malfunction? Reason being, I figure if this holds true, then you can take a total walking measurement of all beds to create a single rectangle for easy calculation of total sq footage. say; 5 beds 14' perimeters ea. = 70 12 trees 4' perimeters ea. = 48 118 total, = 58 sq ft total This can easily be done in your head by taking the total perimiter measurement, substract 2, then divide the remainder by 2 for your total sq footage. I knew I shouldnt have skipped so many algebra classes in high school.
