Jawaban:

[tex] 3.738[/tex] cm²

Penjelasan dengan langkah-langkah:

[tex] \begin{aligned} \rm L &= \rm(p l) + (\pi {r}^{2} ) \\ \rm L& = ( 42 \times 56) + ( \frac{22}{7} \times 21^2)\\ \rm L& = 2.352+ ( 66 \times 21) \\\rm L & = 2.352+ 1.386 \\ \rm L& = \bf 3.738\end{aligned}[/tex]

Jawaban:

3.738 cm²

Penjelasan dengan langkah-langkah:

[tex] l = (p l) + (\pi {r}^{2} )[/tex]

[tex]l =( 42 \times 56) + ( \frac{22}{7} \times 21 \times 21)[/tex]

[tex]\rm l =2.352+ ( 66 \times 21)[/tex]

[tex]l =2.352+ 1.386[/tex]

[tex]l =2.352+ 1.386[/tex]

[tex]l = 3.738[/tex]
