Step-by-step explanation:

PEMDAS:

8^2 + 4 (8 - 14)^2

8^2 + 4 (-6)^2

Exponents second:

8^2 + 4 (-6)^2

64 + 4 (36)

Multiply third:

64 + 4 (36)

64 + 144

Add last and solve:

go on the tube you might find some information there

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.
