Jawab:[a] = 25 cm
Penjelasan:Diketahuia = (3x+2) cmb = (2x+3) cmK = 70 cm
Ditanya diagonal (c)
K = 2(a+b)70 = 2(3x+2+2x+3)70 = 2(5x+5)70/2 = 5x+535 = 5x+55x = 35-55x = 30x = 30/5x = 6
Maka diagonalnya (c)c² = a² + b²c² = (3x+2)² + (2x+3)²nilai x yg tadi = 6, makac² = (3(6)+2)² + (2(6)+3)²c² = (18+2)² + (12+3)²c² = 20² + 15²c² = 400 + 225c² = 625c = √625c = 25
Diagonal (AC) = 25 cmMinta tolong YG SOPAN woy

Jawaban:
K=70
2(p+l)=70
[(3x+2)+(2x+3)]=70/2
5x+5=35
5x=35-5
x=30/5
x=6
p=3x+2=3(6)+2=20cm
l=2x+3=2(6)+3=15cm
AC²=p²+l²=20²+15²=400+225=625
AC=√625=25cm ... (A)

Jawab:
[a] = 25 cm
Penjelasan:
Diketahui
a = (3x+2) cm
b = (2x+3) cm
K = 70 cm
Ditanya diagonal (c)
K = 2(a+b)
70 = 2(3x+2+2x+3)
70 = 2(5x+5)
70/2 = 5x+5
35 = 5x+5
5x = 35-5
5x = 30
x = 30/5
x = 6
Maka diagonalnya (c)
c² = a² + b²
c² = (3x+2)² + (2x+3)²
nilai x yg tadi = 6, maka
c² = (3(6)+2)² + (2(6)+3)²
c² = (18+2)² + (12+3)²
c² = 20² + 15²
c² = 400 + 225
c² = 625
c = √625
c = 25
Diagonal (AC) = 25 cm
