RS = 12 units

Step-by-step explanation:

Ok so first, the line is going between triangle RQS.

Since angle RTS is 90 degrees, angle QTS is also 90 degrees.

These two split triangles are equal, so you can create an equation like so:

2x + 8 = 8x - 4

Add 4 to each side:

2x + 12 = 8x

Subtract 2x from each side:

12 = 6x

Divide each side by 6:

2=x

x=2

Subtitute to find RS:

2x + 8

2 ( 2 ) + 8

4 + 8

12

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.
