tolong jawab dong kak .... Question from @namisyanasution

nxyaptrf

Penjelasan dengan langkah-langkah:

21.

cari dlu panjang sisi diagonal lainnya

= √10² - 8²

= √100 - 64

= √36

= 6

maka, luas nya adalah

= 1/2 × d1 × d2

= 1/2 × 16 × 12

= 16 × 6

= 96 cm²(a)

22.

K = 4s

s = 52/4

s = 13 cm

= √13² - 5²

= √169 - 25

= √144

= 12 cm

Luas

= 1/2 × d1 × d2

= 1/2 × 10 × 24

= 1/2 × 240

= 120 cm² (b)

SOAL 1

___________________________________________

D2 = √S² - (D1 ÷ 2)²

D2 = √10² - (16 ÷ 2)²

D2 = √10² - 8²

D2 = √100 - 64

D2 = √36

D2 = 6 cm

___________________________________________

L Belah Ketupat = ½ × D1 × D2

L Belah Ketupat = ½ × 16 × 12

L Belah Ketupat = ½ × 192

L Belah Ketupat = 96 cm²

Opsi(A.)

___________________________________________

SOAL 2

___________________________________________ S Belah Ketupat = K Belah Ketupat ÷ 4

S Belah Ketupat = 52 ÷ 4

S Belah Ketupat = 13 cm

___________________________________________ D2 = √S² - (D1 ÷ 2)²

D2 = √13² - (10 ÷ 2)²

D2 = √13² - 5²

D2 = √169 - 25

D2 = √144

D2 = 12 cm

___________________________________________

L Belah Ketupat = ½ × D1 × D2

L Belah Ketupat = ½ × 10 × 24

L Belah Ketupat = ½ × 240

L Belah Ketupat = 120 cm²

Opsi(B.)
