Which set of values is a function? 1.(9,5) (10,5) (9,-5) (10,-5)
2.(6,-5) (7,-3) (8,-1) (9,1)
3.(3,4) (4,-3) (7,4) (3,8)
4.(2,-2) (5,9) (5,-7) (1,4)​

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.

you have to stretch your thinking
