*cut off numbers were (5,2)

Answer 1

Area ABCF = AB * BC
Area ABDE = AB * BD
Ratio of (Area ABCF / Area ABDE) = (AB * BC) / (AB * BD) = BC / BD.

Find the lengths of BC and BD and plug it in.

Answer 2

I've tried and can still not figure it out

Answer 3

Use the distance formula. B is (5,2). C is (11,10)
Distance BC = \[\sqrt{(11-5)^2+(10-2)^2} = ?\]

Answer 4

B is (5,2) and D is (14,14)
Distance BD = ?
