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
If the rectangle is enlarged using a scale factor of 5.5, the new dimensions will be:
Length = 8 cm x 5.5 = 44 cm
Width = 6 cm x 5.5 = 33 cm
Therefore, the perimeter of the enlarged rectangle will be:
Perimeter = 2(44 cm + 33 cm) = 2(77 cm) = 154 cm
And the area of the enlarged rectangle will be:
Area = 44 cm x 33 cm = 1,452 cm2
So, the correct answer is:
Perimeter = 154 cm, area = 1,452 cm2
