(b) 60 cm
? Perimeter = 160 cm?
(c) 56.5 cm
25 cm​

Answer 1

Answer:

See Answer's in the Explaination......

Step-by-step explanation:

Perimeter of The Rectangle: 2(l+b)

Perimeter of area=160cm

(a)  L=25cm

     Perimeter = 2(l+b)

                160 = 2(25+b)

                160 = 50+2b

          160-50 = 2b

                 110 = 2b

              110/2 = b

(b)  L=60cm

     Perimeter =2(l+b)

               160 = 2(60+b)

               160 = 120+2b

        160-120 = 2b

                 40 = 2b

              40/2 = b

                  20 = b

c)  L=56.5cm

   Perimeter = 2(l+b)

              160 = 2(56.5+b)

              160 = 113+2b

        160-113 = 2b

                47 = 2b

             47/2 = b
