Which expression is equivalent to 64 – x^2

(8 - x)(8 - x)
(8 - x)(8 +x)
(x - 3)(x - 8)
(X + 8)(x -8)

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.
