Nomor 1:
L = 2(pl + pt + lt)
L = 2(10 × 8 + 10 × 9 + 8 × 9)
L = 2(80 + 90 + 72)
L = 2(242)
L = 484 cm²

Jawaban:
1. 484
2. ⅓
3. 8⁷⁰
Penjelasan dengan langkah-langkah:
♠︎ Math
1. ) Rumus Lp Balok
= 2 × ( Pl ) + ( Pt ) + ( Lt )
= 2 × ( 80 + 90 + 72 )
= 2 × 242
= 484
2. )
[tex] \frac{3}{4} \times \frac{4}{9} = \frac{12}{36} \div 12 = \frac{1}{3} [/tex]
3. ) 8⁹⁰ ÷ 8²⁰ = ?
= Jika Aⁿ ÷ A^m Maka Rumusnya = Aⁿ - ^M Jadi,
= 8⁹⁰ ÷ 8²⁰ = 8⁹⁰ - ²⁰ = 8⁷⁰
