Jawaban:

a. 24 cm

b. 288 cm

c. 76 cm

Penjelasan dengan langkah-langkah:

DIKETAHUI :

• AB = 25

• BD = 7

• CD = 10

• AC = 26

• BC = AD = 24

a. AD² = AB² - BD²

= 25² - 7²

= 625 - 49

AD = √576

AD = 24

b. Luas segitiga

= 1/2 x a x t

= 1/2 x BC x BA

= 1/2 x 24 x 25

= 12 x 24

= 288

c. Keliling segitiga

= a + 2b

= 24 + 2(26)

= 24 + 52

= 76
