3. What is the perimeter of a rectangle if the width is 2 ½ inches and the length is 4.5 inches? (show how you get your answer please)

Perimeter of the rectangle =  14 inches

Step-by-step explanation:

Step(i):-

Given length of the rectangle = 4.5 inches

Given that the width of the rectangle = inches

The area of the rectangle = length × width

                                          = 4.5 × 2.5

                                          = 11.25 sq inches

Step(ii):-

Perimeter of the rectangle = 2( length + width)

                                            = 2( 4.5 + 2.5)

                                            = 14 inches

Final -

Perimeter of the rectangle =  14 inches
