Art can do a job working alone in 8 hours. After he has been working alone for 3 hours, he is joined by Cathy, who is the faster worker. They finish the job in 2 more hours. How long would it have taken Cathy if she worked alone?

very simple

Step-by-step explanation:

me is very poor

is there any photos or whatever?

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.
