What is 7/8+8/9?I really need to know.

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.

answer:

your answer is: c. 196 7/8 in^3.

6mm^3 or .6cm^3

6     6   6

factor trees are nice.
