Tolong dibantu yahh nanti aku jadikan jawaban terbaik klo benar........

Answer 1

Verified answer

Bangun Datar

Gambar 1
L arsiran = L persegi - L 1/2 lingkaran
= (s x s) - (1/2 x π x r x r)
= (14 x 14) - (1/2 x 22/7 x 7 x 7)
= 196 - (11 x 7)
= 196 - 77
= 119 cm^2

Gambar 2
L arsiran = 2 (L 1/4 lingkaran - L segitiga)
= 2 (1/4 x π x r x r - 1/2 x a x t)
= 2 (1/4 x 3,14 x 10 x 10 - 1/2 x 10 x 10)
= 2 (1/4 x 314 - 5 x 10)
= 2 (78,5 - 50)
= 2 x 28,5
= 57 cm^2

*semoga membantu. sukses selalu ^_^
