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

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
