Question

If the length of a rectangle is 7m less than twice its breadth and its perimeter is 250 m. Find its length and breadth.​

Answer 1

Answer:

Sol-

   Let length be l and breadth be b,

By question,

 l=2b-7

Perimeter(p)=250m

We know,

         p=2(l+b)

         250=2(2b-7+b)

         250=6b-14

         250+14=6b

          264/6=b

           b=44                      

     Again,

       l=2b-7

        l=2*44-7

          l=88-7

           l=81

• ∴ The length is 81m and breadth is 44m .
