Diketahui persegi panjang mempunyai panjang 3x 1 cm dan lebar x 4 cm jika keliling persegi panjang tersebut 30 cm hitunglah luasnya bantu bre

Posted on

Materi : Bentuk Aljabar

K = 2p + 2l

30 = 2( 3x – 1 ) + 2( x + 4 )

30 = 6x – 2 + 2x + 8

30 = 8x + 6

30 – 6 = 8x

24 = 8x

\__________________/

Result / hasil :

3 cm = x

8 cm = ( 3x – 1 ) [ panjang ]

7 cm = ( x + 4 ) [ lebar ]

____________________

Luas Persegi Panjang

L = p × l

L = 8 cm × 7 cm

L = 56 cm²

Semoga bisa membantu
