Mapel : Matematika
Bab : Teorema phytagoras

alas^2 = 20^2 - 12^2
alas^2 = 400 - 144
alas^2 = 256
alas = akar 256
alas = 16 cm

L = 1/2 × alas × Tinggi
L = 1/2 × 16 × 12
L = 8 × 12
L = 96 cm^2

Please, let me answer your question :)

Pertanyaan yg diajukan : 1
Pembahasan :

Diketahui :
- Sisi Miring (C) : 20 m
- Tinggi (t) : 12 m

Ditanya :
- Luas (L)

- Cara :

Kamu harus mencari Alasnya (a) terlebih dahulu :

a² = C² - t²
a² = 20² - 12²
a² = 400 - 144
a = √256
a = 16 m

Masuk ke rumus Luas Segitiga :

L = ½ x a x t
L = ½ x 16 x 12
L = 8 x 12
L = 96 m²

Jawaban : D
