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.
