Solve segitiga alas 10, tinggi 6 — A = 30

Method: rumus luas segitiga. Verified step-by-step solution with our free AI math solver.
Problem

A=12bh, b=10, h=6A = \tfrac{1}{2} b h,\ b=10,\ h=6

Step-by-step solution

  1. Terapkan: A=12baseheightA = \tfrac{1}{2} \cdot \text{base} \cdot \text{height}.

  2. Substitusikan b=10b = 10, h=6h = 6: A=12106A = \tfrac{1}{2} \cdot 10 \cdot 6.

  3. Sederhanakan: A=30A = 30.

  4. Catatan: tinggi harus tegak lurus terhadap alas yang dipilih — bukan panjang sisi miringnya.

Answer

A=30A = 30
