Perimeter is equal to the sum of all sides, in this case 2 of the length of the rectangle plus 2 of its width: 2*8 units +2*4 units ______ 16 + 8 =24 units
2 times 8= 16, the area is 16 units
units are what your talking about. 8 units would be 8 of whatever ur talking about. EX: You have 6 Hotdogs at home and need 2 more. How many hotdogs do you need in all? 6 hotdogs+2 Hotdogs= 8 Hotdogs in this example 8 units would be the 8 Hotdogs
Cylinder V = (pi) r2 h = 3.1416 x (2 units)2 x 8 units = 100.5 cubic units
No. -2 is six units from it, but 8 is only four units from it.
