Mrs. smith has bolts of material that have lengths of 42, 63, and 105 inches. she needs to cut the fabric into equal length pieces with none left over. what is the greatest length of fabric pieces she can cut?

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.

idk man good luck man
