Question
The length of a plot is six times its breadth. A
playground measuring 192 square metres occupies half of the total area of the plot. What is the length of the plot?Solution
Using formula, Area = lb, Let breadth of plot = x metre Length = 6x metre According to question, ⇒ 6x2/2 = 192 ⇒ x2 = (192 x 2)/6 = 64 ⇒ x= 64 metre Therefore, length = 6 x 8 = 48 metre
