Answer:
Step-by-step explanation:
width=√(130²-120²)=√[10²(13²-12²)]=10√(13+12)(13-12)=10√(1×25)=10×5=50 m
perimeter=2(120+50)=2×170=340 m
area=120×50=6000 m²
I think your answer would be A?
1/2, 3/6, 4/8, 5/10, etc.
It looks like you have to do distance formula. It's basically this:
D =
(ignore the A, i dont know how to get rid of it sorry)
I would then plug in the points of A(1,7) and B(10,3).
D = 
Then I would get the square root of 4^2 + 9^2
= square root of 16 + 81
= square root of 97
So the length of AB would be the square root of 97
