Materi : Bangun Datar
Soal Nomor 3
Bagian A
K = 2( p + l ) = 2( 17 + 9 ) = 2( 26 ) = 52 cm
L = pl = 17.9 = 170 - 17 = 153 cm²
Bagian B
K = 2( 20 + 5 ) = 2( 25 ) = 50 cm
L = 20.5 = 100 cm²
Bagian C
K = 2( 25 + 6 ) = 2( 31 ) = 62 cm
L = 25.6 = 150 cm²
Soal Nomor 4
2( p + l ) = K
2( p + 4 ) = 28
p + 4 = 14
[ p = 10 ]
---
L = 10.4 = 40 cm²
Soal Nomor 5
L/m² × Rp 50.000
= ( pl )/m² × Rp 50.000
= ( 30 × 20 ) × Rp 50.000
= 600 × Rp 50.000
= Rp 30.000.000
Soal Nomor 6
p : l = 3 : 2 = 3x : 2x
2( p + l ) = 100
3x + 2x = 50
5x = 50
[ x = 10 cm ]
Hasil / Result :
p = 3x = 3(10) = 30 cm
l = 2x = 2(10) = 20 cm
Semoga bisa membantu

3)
A) K = 2P + 2L
= 2(17) + 2(9)
= 34 + 18
= 52 CM
L = P(L) = (17(9)
= 154 CM²
B) K = 2P + 2L
= 2(20) + 2(5)
= 40 + 10
= 50 CM
L = P(L)
= (20(5)
= 100 CM²
C) K = 2P + 2L
= 2(25) + 2(6)
= 50 + 12
= 62 CM
L = (25(6)
= 150 CM²
4) K = 2(P + L)
28 = 2(P + 4)
28/2 = P + 4
14 = P + 4
P + 4 = 14
P = 14 - 4
P = 10 CM
L = P(L)
= (10(4)
= 40 CM
5) (30(20(50.000)
= (600(50.000)
= 30.000.000
6) 2(3X + 2X) = 100
(3 + 2)X = 100/2
5X = 50
X = 50/5
X = 10/1
X = 10
MAKA :
P = 3 × 10 = 30 CM
L = 2 × 10 = 20 CM
