Problems On Area




     1.  The difference between length and                  breadth of a rectangle is 23m.If a                    perimeter is 206 m, then it's area is:

Answer:   we have (l-b)=23 and 2(l+b)=206
                  Solving two equations we get                           :l=63,                b=40
 Hence, Area =(l*b)=63*40=2520m*m
