K = 2p + 2l
44 = 2(3x+4) + 2(2x+3y)
44 = 6x+8 + 4x +6y
36 = 10x + 6y
x = 3 dan y = 1
Maka panjang
3(1) + 4 = 13 cm
dan lebar 2(3) + 3(1) = 9 cm
Semoga membantu CMIIW
44 = 2 (3x + 4 + 2x + 3)
44 = 2 (5x + 7)
44 = 10x + 14
10x = 44 - 14
10x = 30
x = 3
panjang = 3x + 4
= 3.3 + 4
= 13 cm
lebar = 2x + 3
= 2.3 + 3
= 9 cm
semoga membantu :)
