The length of the rectangle is triple its breadth. If
the perimeter of the rectangle is 160 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) 160 = 2(x + 3x) 80 = 4x x = 20 Breadth = 20 m, Length = 60 m So the area of the rectangle = 20 × 60 = 1200 m2
