tolong jawab plis buat bsk pagi

L1=a×t÷2

=14×14÷2

=98cm2

L2=22/7×14×14

=616cm2

=616×1/4

=154cm2

=616-154=462

L total=462+98

=560cm2

maaf kalau salah

Rumus 3/4 lingkaran = r × r × 22/7×3/4
=14 × 14 × 22/7 × 3/4
=616×3/4 = 462 cm2.
Rumus segitiga = p × l × 1/2
= 14×14÷2
=196÷2 = 98 cm2.
Total = 462cm2+98cm2 = 560 cm2
