Answer 1

sorry m not good at geometry

Answer 2

its ok Im not either lol I appreciate you looking for me though :)

Answer 3

BC =72

Answer 4

AB=56

Answer 5

do I just add them together

Answer 6

yes

Answer 7

128 feet

Answer 8

see its a problem of similar triangles

Answer 9

Thank you!

Answer 10

QB/QP= BC/PR
60/100=BC/120
BC=72
similarly QC/QR= BC/PR
QC/140=72/120
QC=84
Rc= QR-QC= 140-84=56
hence length of fence = AB+BC
56+72=128
