What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 4.5? a rectangle is shown. the length of the rectangle is labeled as 8 cm, and the width is labeled as 6 cm. a. perimeter = 46 cm, area = 131.25 cm2 b. perimeter = 126 cm, area = 972 cm2 c. perimeter = 46 cm, area = 972 cm2 d. perimeter = 126 cm, area = 131.25 cm2

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
