[B]Problem:

A farm has a perimeter of 55 km and has an area of 150 km sq. Find the dimensions of the farm.

i tried to answer on this that

A= l x w P = 2 (l + w)

150 km sq. = l x w 55 km = 2 (l +w)

what is next to here? do i need to manipulate the formula? i'm stuck here.

Please does anybody can help me on this?

Thank you
