What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 6.5? (5 points)
A rectangle is shown. The length of the rectangle is labeled as 8 cm, and the width is labeled as 6 cm.
Perimeter = 54 cm, area = 181.25 cm2
Perimeter = 54 cm, area = 2,028 cm2
Perimeter = 182 cm, area = 2,028 cm2
Perimeter = 182 cm, area = 181.25 cm2

Perimeter = 182 cm, area = 2,028 cm2
Step-by-step explanation:
original perimeter=2*(8+6)+28 cm
original area=8*6= 48 cm²
You would have to do the old length and width times the scale factor
Multiply both of the width's
8 * 6.5 = 52 cm
scale factor: 6 * 6.5 = 39 cm
To get perimeter = 2(length + width)
2(52+39)=182 cm.
So you would have to do length(52 cm) * width(39 cm)
To get 2028 cm^2
