Can someone tell me the answer to this

1.423 x

5.78 x

Step-by-step explanation:

Scientific notation is a way of denoting a quantity as a single-digit number followed by decimals, times a base of ten.

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.
