Answer 2

Answer:

therefore, breadth is 45 cm and  Area is 3150 cm^2

Step-by-step explanation:

perimeter of rectangle = 230 cm

length of the rectangle = 70 cm

breadth :-

P of rectangle= 2(l+b)

                 230=2(70+b)

                  230=140+2 b

                 230-140=2 b

                      90   =2 b

                       90/2=b

                          45=b

therefore, breadth is 45 cm.

Area= l x b

       =70 x 45

       =3150 cm^2

therefore, Area is 3150 cm^2
