Jawaban:
alas = √(10² - 8²) = √36 = 6 cm
Luas = 1/2 × a × t = 1/2 × 6 × 8 = 24 cm²
K = a + b + c = 8 + 6 + 10 = 25 cm
[ Opsi A ]
A. 24 cm² dan 24 cm
Penjelasan dengan langkah-langkah:
rumus pythagoras
B = √A²-C²
B = √10²-8²
B = √100-64
B = √36
B = 6
rumus keliling
sisi+sisi+sisi
10+8+6 = 24 cm
rumus luas
alas x tinggi : 2
6 x 8 : 2
= 24cm²
