()“cheyenne has seventy marbles and gives 2/5 to her friend niome. niome then gives 1/4 to mary. how many marbles did niome keep? ”

I believe the answer is 21. I can tell you how I got the answer if you want.

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.
