Q:

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

Accepted Solution

A:
The perimeter of the rectangle is by definition:
 P = 2W + 2L
 Where,
 W: width
 L: long
 We have then:
 P = 2 (5.5 * 6) +2 (5.5 * 8)
 P = 154 cm

 The area of the rectangle is by definition:
 A = (W) * (L)
 Where,
 W: width
 L: long
 We have then:
 A = (5.5 * 6) * (5.5 * 8)
 A = 1452 cm ^ 2

 Answer:
 Perimeter = 154 cm, area = 1,452 cm2
