Question

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.

Group of answer choices

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

Answer 1

If we enlarge the rectangle by a factor of \(6.5\), then the length goes to \(6.5 \times 8=52\textrm{ cm}\) and the width goes to \(6.5 \times 6 = 39\textrm{ cm}\).
Can you now calculate the new area and the new perimeter?
