Solve rectangle 8 by 5

Method: rectangle area formula. 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. For a rectangle: A=l×wA = l \times w (length × width).

  2. Substitute l=8l = 8 and w=5w = 5.

  3. A=8×5=40A = 8 \times 5 = 40.

  4. Units are squared (e.g. cm² if both sides are in cm).

Answer

A=40A = 40
