Answer 1

Answer:

perimeter of the rectangle=2(l+b)

320=2(?+60)

320/2=?+60

160=?+60

160-60=?

100=?

Answer 2

Answer:

120 cm

Step-by-step explanation:

Given perimeter = 320 cm

breadth =  60 cm

length = ?

steps to find length :-

perimeter of rectangle = 2(L+B)

320 = 2( L+60 )

      = 2L + 120

 2L  = 360 - 120

       = 240

  L   = 240/2

       = 120

Therefore, length is equal to 120 cm.
