Question
The length of the rectangle is triple its breadth. If
the perimeter of the rectangle is 96 m, then find the area (in m2) of the rectangle.Solution
Let the breadth of the rectangle = x, so the length of the rectangle = 3x Perimeter = 2(l + b) 96 = 2(x + 3x) 48 = 4x x = 12 Breadth = 12 m, Length = 36 m So the area of the rectangle = 12 × 36 = 432 m2
