Question

The area of a rectangular field whose length is twice its breadth is 2450m^2. Find the perimeter of the field.

Answer 1

Answer:

the perimeter 210 metres

Step-by-step explanation:

we have l=2b........(1)

where l is length and b is breadth

we have that area =2450m^2

so , l×b =2450 2b^2=2450............(from eqn.1)

b^2=1225

b =35 metre

so, l=2(35)

l=70 metre

now perimeter=2(l+b) =2(35+70) metres =210 metres
