Question

The perimeter of a rectangle is 240 cm if its length is increased by 10

Answer 1

Answer:

breadth = 55

length  =65

Step-by-step explanation:

Let breadth = x

length = x+10

perimeter of rectangle =  240

      2(l+b)     =240

      2(x+10+x)=240

        (2x+10)=240/2

         2x = 120 -10

         2x=110

          x= 55

∴ breadth = x= 55

length = x+10 = 55+10 =65
