What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 5.5? A rectangle is shown. The length of the rectangle is labeled as 8 cm, and the width is labeled as 6 cm. Perimeter = 50 cm, area = 155.25 cm2 Perimeter = 50 cm, area = 1,452 cm2 Perimeter = 154 cm, area = 155.25 cm2 Perimeter = 154 cm, area = 1,452 cm2
To find the new dimensions of the enlarged rectangle, we need to multiply the original dimensions by the scale factor of 5.5.
New length = 8 cm x 5.5 = 44 cm
New width = 6 cm x 5.5 = 33 cm
Now we can calculate the perimeter and area of the enlarged rectangle:
Perimeter = 2(44 cm) + 2(33 cm) = 88 cm + 66 cm = 154 cm
Area = 44 cm x 33 cm = 1,452 cm2
Therefore, the correct answer is:
Perimeter = 154 cm, area = 1,452 cm2
