Step-by-step explanation:
- a . write the formula for finding area that is area= L by W so to get w will area over length so 4731/83= 57
- perimeter=2( L+ W ) so substitute so that it looks like this 318= 2(L + 72 ) then open the bracket 318= (2L + 144) then move 144 to the other side so 318 - 144 = 2L then you get 174= 2L divide both sides by 2 and your length is 87

10P8 = 10!/(10 - 8)! = 10!/2! = 1,814,400
3)the line G & H are parallel
4) Parallel line theorem is what I do believe it's called (do you have choices for this one?)
