The area of a rectangle is represented by the function x^3 − 2x^2 − 40x − 64.

The width of the rectangle is x + 4. Find the expression representing the length of the rectangle.

x^2 − 8x − 20
x^2 + 12x + 20
x^2 − 6x − 16
x^2 + 10x + 16

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.
