Most breccias are a mix of rock fragments and mineral grains. The type of rock that the fragments were produced from is often used as an adjective when referring to the rock. Some examples: sandstone breccia, limestone breccia, granite breccia, chert breccia, basalt breccia and others.hen you hear the word breccia used in reference to a rock or rock material it is fairly safe to assume that it means angular-shaped pieces. The rock, breccia, has very few uses. However, the word breccia is used as a trade name for a group of dimension stone products with a broken, angular pattern.
One acre is a measure of area which is equal to 4840 sq yd or 1/640  square mile. It does not matter what shape it has.    Historically an acre was the amount of land â¦ a set of oxen could  plough in 1 day.nswer by Ablex. Confidence votes 824. There are 43,560 square feet in one acre so take the length times the width in feet and divide by that figure to find the number or fraction of an acre. If the property is irregular, take length times width of each roughly rectangular chunk and add them together before dividing.
The Answer: Because an acre is a measure of area, not length, it is defined in square feet. An acre can be of any shapeâa rectangle, a triangle, a circle, or even a starâso long as its area is exactly 43,560 square feet.The most standard shape for an acre is one furlong by one chain, or 660 feet by 66 feet.To find the linear measurements of other rectangular acres, just divide 43,560 by the number of feet you want on one side.A square-shaped acre would then be about 208.7 by 208.7 feet (because 208.7 x 208.7 = ~43,560).An acre 100 feet wide would be 435.6 feet long (100 x 435.6 = 43,560) and an acre 1 foot wide would be 43,560 feet long. square-shaped acre would then be about 208.7 by 208.7 feet (because 208.7 x 208.7 = ~43,560). An acre 100 feet wide would be 435.6 feet long (100 x 435.6 = 43,560) and an acre 1 foot wide would be 43,560 feet long.
