Answer 2

Concept: Perimeter is the total boundary of the rectangle.

Perimeter of the rectangle is double of sum of length and width.

Given: Perimeter of the rectangle is 28 cm.

Find: Calculate the width of the rectangle.

Solution: Let the length of the rectangle is l.

Width of the rectangle is (l-3) cm

Perimeter of the rectangle = 2(length+width) =28 cm

                                            = 2(l+l-3) =28 cm

                                            = 2(2l-3) =28 cm

                                            = 4l-6=28 cm

                                            = 4l=28+6

                                            = 4l=34

                                            = l=34/4

                                            = l=8.5 cm

Length of the rectangle is 8.5 cm.

Width of the rectangle is l-3

                                        = 8.5-3

                                        = 5.5 cm

Final answer: Width of the rectangle is 5.5 cm.
