Perimeter is 46 because it is 8+16+6+4+12
To find the area split up the two shapes, the bigger one is 8 times 12 which is 96 then the second shape has an area of 4 times 6 which is 24, add those together and the area of the whole shape is 120.
For the first question, it is cos48=2/3
All States except Delaware, South Dakota, Alaska, North Dakota, Vermont & Wyoming.(6 states doesnt)
Cutting, grinding, and drilling are other ways diamonds can be used
What are your question options ?
