Question
Ratio of length to width of a rectangular field is 5:4. 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 β5xβ metres and β4xβ metres, respectively. So, 2(5x + 4x) = 360 Or, x = 20 Area of the field = 5x Γ 4x = 6 Γ (20)2 = 8000 m2
