Answer 1

Answer:

given, sides of the rectangle are in the ratio 4 is to 5 and perimeter of rectangle is 19 cm

Explanation:

perimeter of the rectangle= 2(l+b)

                                     19=2(5x+4x)

                                   19=2(9x)

                                 19=18x

                                19/18=x

                           ∴ x=19/18
