Minta tolong jawabanyaa,sama cara yahhh

Luas Bangun disamping
= L. Segitiga + L. 1/2 Lingkaran
= (1/2×28×(34 – (28÷2)) + (1/2×22/7×14×14)
= (14×20) + (22×14)
= 280 + 308
= 588 cm2

Sekian dan terima kasih

L1 = segitiga
L2 = setengah lingkaran

t segitiga = p keseluruhan – jari jari lingkaran 34-14 =20

$l1 = frac{1}{2} a times t \ frac{1}{2} times 28cm times 20cm = 280 {cm}^{2} \ \ l2 = frac{1}{2} times frac{1}{4} times pi times {d}^{2} \ = frac{1}{8} times frac{22}{7} times 28cm times 28cm \ = 308 {cm}^{2} \ \ l : total : = l1 + l2 = 280 {cm}^{2} + 308 {cm}^{2} = 588 {cm}^{2}$
semoga membantu dan jadi jawaban terbaik
