Question

The length of rectangle is 7 m more then its breath if its perimeter is 50 m. find the length and breath of the rectangle

Answer 1

hope this will help you....

Answer 2

length=x
breadth=y
ACQ.-
x=7+y
perimeter of rectangle=2(x+y)=50
2x+2y=50
2(x-y=7)


therefore solving by elimination method,we get
2x+2y=50
2x-2y=14
--------------
     4x=64
       x=64/4
x=16
therfore length =16
breadth(y)=2x+2y=50
                   2(16)+2y=50
                    2y=50-32
                       y=18/2
                       y=9
therefore breadth =9

i hope this will help u!!!!
