Solve 8 × 5 的矩形

Method: 矩形面積公式. Verified step-by-step solution with our free AI math solver.
Problem

A=l×w, l=8, w=5A = l \times w,\ l=8,\ w=5

Step-by-step solution

  1. 對於矩形:A=l×wA = l \times w(長 × 寬)。

  2. 代入 l=8l = 8w=5w = 5

  3. A=8×5=40A = 8 \times 5 = 40

  4. 單位是平方(例如兩邊都以 cm 為單位時就是 cm²)。

Answer

A=40A = 40
