If you round the 6. Or if they ask u to round the tenth place or ones place and do the opposite or something else
Sylvia puts in $121.
10% of (multiply) $210.
210= 100 each person plus an additional ten from Leroi
so .10*210 = $21.
Add Sylvia's $100 plus $21 and viola, $121
The perimeter would be 7+7+4+4 or 14+8 which equals 22 and the area would be 7x4 which is 28
I think You should break it down to the First and third One because of
If m1 and m2 are the slopes of each line, for them to be perpendicular you gotta solve
m1 * m2 = -1
