Question
The length of the rectangle is triple its breadth. If
the perimeter of the rectangle is 120 m, then find the area (in m 2) of the rectangle.Solution
Let the breadth of the rectangle = x, so the length of the rectangle = 3x Perimeter = 2(l + b) 120 = 2(x + 3x) 60 = 4x x = 15 Breadth = 15 m, Length = 45 m So the area of the rectangle = 15 × 45 = 675 m2
