Question
Ratio of length to width of a rectangular field is 3:2.
If the perimeter of the field is 360 metres, then find the area (in m2) of the field.Solution
Let length and width of the rectangular field be ‘3x’ metres and ‘2x’ metres, respectively. So, 2(3x + 2x) = 360 Or, x = 36 Area of the field = 3x × 2x = 6 × (36)2 = 7776 m2
