6.92 x 10 to the power of negative 8
in standard notation

0.0000000692

Step-by-step explanation:

The number is written in scientific notation. To convert to standard notation adjust the decimal point to adjust the number according to the exponent. Since the exponent is -8 then the decimal point moves to the left 8 place values.

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.
