The height of a stack of DVD cases is in a proportional relationship to the number of cases in the stack. A stack of 6 cases and its height are shown. The height of 6 DVD cases is 66 mm. Find the constant of proportionality. Then use the constant of proportionality to find the height of a stack of 14 cases.

The answer is 11 becasue 66 divided by 6 equals 11

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
