Question

The length of the plot of land is 4 times its breadth.A playground measuring 1200 sq. M. Occupies one-third of the total area of the plot.What is the length of the plot in metres?

Answer 1

Answer:

120m

Step-by-step explanation:

Area of the plot = (3 x 1200) m2

= 3600 m2

Let breadth = y meters

Then Length = 4y meters,

Now area = 4y x y = 3600 m2

⇒ y2 = 900 m2

⇒ y = 30 m

∴ Length of plot = 4y m

= (4 x 30) m

=120 m
