please! dijawab ya.. beserta caranya

Keliling Persegi Panjang 1 = 2 × ( p + l )
= 2 × ( 5 + 2 )
= 2 × 7
= 14
Keliling Persegi Panjang 2 = 2 × ( p + l )
= 2 × ( 10 + 12 )
= 2 × 22
= 44
Keliling Persegi Panjang = 2 × ( p × l )
= 2 × ( 4 + 2 )
= 2 × 6
= 12

Keliling Gabungan Bangun Datar Diatas = 24 + 44 + 12 = 80 cm
Jawabannya d. 80 cm
