Kak, tolong kerjain yaa, bsok dikumpul, Kerjainnya yang dilingkar aja ya!

-NO. 2-

keliling jajar genjang ABCD = 2(3x-3)+2x
10 = 6x-6+2x
10+6 = 8x
8x = 16
x = 2

EF = AB = 3x-3 = 3(2)-3 = 3

FG = BC = x = 2

CH = CD = 3x-3 = 3(2)-3 = 3

HE = DA = x = 2

-NO.3-

AB = EF
3 = 3x
x = 1

EF = 3x = 3(1) = 3

FG = √(3x-x)²+(2x+1)²
FG = √(3(1)-1)²+(2(1)+1)²
FG = √4+9 = √(13)

GH = x = 1

HE = 2x+1 = 2(1)+1 = 3
