Question
The length of a plot is eight times its breadth. A
playground measuring 256 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 = 8x metre According to question, ⇒ 8x2/2 = 256 ⇒ x2 = (256 x 2)/8 = 64 ⇒ x = 8 metre Therefore, length = 8 x 8 = 64 metre       Â
