Question
The length of a plot is seven times its breadth. A
playground measuring 224 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 = 7x metre According to question, ⇒ 7x2/2 = 224 ⇒ x2 = (224 x 2)/7 = 64 ⇒ x = 8 metre Therefore, length = 7 x 8 = 56 metre
