bantu saya ya kakak kakak

Luas persegi = s x s
L = 20 x 20
L = 400 cm²

Luas segitiga
L = 1/2 x a x t
L = 1/2 x 20 x 6
L = 10 x 6
L = 60 cm²

Luas setengah lingkaran
D = 20 cm
r = D/2 = 20/2 = 10 cm

L = 1/2 x π x r²
L = 1/2 x 3,14 x 10²
L = 1/2 x 3,14 x 100
L = 157 cm²

Luas Bangun
L = 400 cm² - 60 cm² - 157 cm²= 183 cm²

luas persegi
= s × s
= 20 × 20
= 400 cm2

luas 1/2 lingkaran
= 1/2 × π r kuadrat
= 1/2 × 3,14 × 10 × 10
= 1/2 × 314
= 157 cm2

luas segitiga
= 1/2 × a × t
= 1/2 × 20 × 6
= 1/2 × 120
= 60 cm2

luas daerah yang diarsir

400 cm2 - ( 157 cm2 + 60 cm2 )
400 cm2 - 217 cm2
= 383 cm2
