How To Find Area Of A Rectangle?

Identify the rectangle’s length (L)

Identify the rectangle’s width (W)

Use the formula: Area = L × W

If given perimeter (P) and one side, find the other side: W = P/2 − L

Then compute: Area = L × W

If given diagonals (d1, d2) and it’s a rectangle: Area = (d1 × d2) / 2
