1. Alice is making a necklace. She has a chain that is 400 mm long. She puts forty 1.7 mm beads, twenty-seven 612 mm beads, and eight 3.4 mm beads on the chain. About how
much of the 400 mm chain is left without beads?
A 388 mm
B. 270 mm
C. 230 mm
D. 129 mm

answer: 1 and 3

step-by-step explanation:

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.
