The element silicon is used extensively as a semiconductor in solid-state devices in the computer and microelectronics industries. For this, hyperpure silicon is needed. The silicon is selectively doped with tiny amounts of boron, gallium, phosphorus or arsenic to control its electrical properties.
Â· just now. Asker's rating. Report Abuse. An acre is a measure of area that I will call A for now. L*W = A which gives L = A/W C = 2*(L + W) = 2*(A/W + W) So, as you can see, the circumference depends on the width (or L, whichever way you want to look at it).
So an square acre is 208.71 feet by 208.71 feet.For an acre that has a rectangular shape, the area formula is given as length multiplied by the width. Since the area is 43,560 square feet, the multiplication of length by width dimensions of the acre must be equal to this area. This means that a rectangular acre can have any dimensions, such as 1 foot by 43,560 feet, 2 feet by 21780 feet, 10 feet by 4356 feet or 660 ft by 60 feet.
