Question

Peremeter of rectangle is 30m its length is 10 m find its breadth

Answer 1

Given Data:

      perimeter of rectangle=30m

         length of rectangle    = 10m

To Find:

         The breadth

solution:

    ∴Perimeter of rectangle = 2(l+b) units

                    30 = 2(10+b)

                    30=20+2b

              30-20=2b

                  10   =2b

                   $b=\frac{10}{2}$

                   b=5m

∴The breadth of the rectangle is 5 m
