Well if it’s a square all sides are equal, so all sides are 7ft.
Perimeter=
7+7+7+7=28ft
Or
7•4=28
Hope this helps!!!
Answer:
1 and 3 are both perpendicular to segment NY
Step-by-step explanation:
1. Find the slope of line NY
slope of NY = 5-(-7)/-11-5 = - 3/4
Any line that is perpendicular to NY should have a slope of the inverse of negative slope of NY.
2.Find the slope of perpendicular lines
the inverse of negative slope of NY = - (-4/3) = 4/3
4(9+7-9)
the nines cancel
4*7 =28
