Step-by-step explanation:
Xm = (-3+3)/2 = 0/2 = 0
Ym = (2-2)/2 = 0/2 =0
so, the midpoint (Xm, Ym) is (0 , 0)
9x+x=5. or 9x+x+5=0 but probably the first one
Area=legnth times width
legnth=30 and 1/2
width=20
area=30 and 1/2 times 20
area=(30+1/2) times 20
distribute
area=20 times 30+20 times 1/2
area=600+10
area=610
area= 610 m^2
perimiter=legnth +width+legnth+width
perimiter=2legnth+2width
width=6 and 1/2
legnth=10
perimiter=2(10)+2(6 and 1/2)
perimiter=20+13
perimiter=33cm
1. area=610 m^2
2. perimiter=33cm
