Only circles have a circumference but if you mean its perimeter it is 6+6+2+2 = 16 meters
If you are talking about a rectangle, just multiply 5 x 6. The answer will be in square meters.
It is 48 square metres.
36 square meters
Length of rectangle: 240/15 = 16 meters
The width of the rectangle is 13 meters. The perimeter of the rectangle is 50 meters, and its length is 12 meters. The 50 meters is 2 times the length plus 2 times the width. With a length of 12 meters, twice that is 24 meters. That leaves 50 meters - 24 meters for twice the width. And 50 - 24 = 26, which is twice the width. The 26 meters divided by 2 = 13 meters, which is the width of the rectangle.
Circle.
144 cubic metres. To find the area of a cube, you multiply length times width times height. Thus, 6*6*4=144
