Question

What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 4.5? A rectangle is shown. The length of the rectangle is labeled as 8 cm, and the width is labeled as 6 cm. A.Perimeter = 46 cm, area = 131.25 cm2 B.Perimeter = 126 cm, area = 972 cm2 C.Perimeter = 46 cm, area = 972 cm2 D.Perimeter = 126 cm, area = 131.25 cm2

Answer 1

Answer: perimeter is 126

Area is 972cm

Step-by-step explanation:

Answer 2

The correct answer would be B, P=126 - A=972

If the scale factor is 4.5, you would multiply both the width and the height by 4.5
which gets you the dimensions of 36 by 27.
P=2w+2h
P=36(2)+27(2)
P=72+54
P=126
-
A=bh
A=(36)(27)
A=972

Hope this helps!
