Step-by-step explanation:

We need to find the perimeter

AB = 30+20 = 50

BC = 45

CD = 30

DE =x

EF = 20

FA = 45-x

I think of it as slide  FA to match up to  ED and together they make 45  (the same distance as BC)

The perimeter is AB + BC+ CD + DE + ER + FA = 50+45+30+x+20+45-x = 190

The fence is bought in 5 foot sections so we need to determine how many sections

190/5 = 38

We need 38 sections at 7.50 each

44*7.50 =285 dollars

Total cost = installation plus fence

                 =500+285 = 785
