Key Insights
To find the area of a rectangle where length equals three times width and perimeter equals 64, begin with the key formulas: perimeter = 2(length + width), and area = length × width.
Let the width be w. Then the length is 3w.
Substitute into the perimeter equation:
2(3w + w) = 64
2(4w) = 64
8w = 64
w = 8
So the width is 8 units. The length, being three times the width, is 3 × 8 = 24 units.
Now calculate the area:
Area = width × length = 8 × 24 = 192 square units.
