The breadth of a rectangular field is 60% of its length. If the perimeter of the field is 800 m, find out the area of the field.
Choose the correct choice from the following answers:
A) 37500	B) 38000	C) 38500	D) 39000	E) 39500
Given that breadth of the rectangular field is 60% of its length.   ⇒b=60l100=3l5   perimeter of the field =800 m   ⇒2(l+b)=800⇒2(l+3l5)=800⇒l+3l5=400⇒8l5=400⇒l5=50⇒l=5×50=250 m   b=3l5=3×2505=3×50=150 m   37500rea =lb=250×150=37500 m2   37500nswer is 37500.
