The fence should be measured in just feet
the answer is B. ft.
I remember doing that yesterday i could get it for tmwr
1) 200x10=2000 then 1/10 = 200
2) 10x10=100= then 1/10 = 10
3) 700x10= 7000 then 1/10 = 700
4) 5000x10=50000 then 1/10 = 5000 Hopefully that helps you ❤
add 3.7 and 4.45 make sure to change it back to standard you'll get 815000000000000000000. move decimal between first and second digit which means you moved it to the left 18 times and your answer will be 8.15 x 10 ^18 I hope its right :( please don't judge if wrong :((( lol
