Please help! What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 4.5? ^ means squared A.) Perimeter = 46 cm, area = 131.25 cm^2 B.) Perimeter = 126 cm, area = 972 cm^2 C.) Perimeter = 46 cm, area = 972 cm^2 D.) Perimeter = 126 cm, area = 131.25 cm^2

B.) Perimeter = 126 cm, area = 972 cm²

Step-by-step explanation:

==>Given:

Rectangle with the following dimensions:

L = 8 cm

W = 6 cm

==>Required:

Perimeter and area of the rectangle if enlarged using a scale factor of 4.5.

==>Solution:

The dimensions of the rectangle when enlarged by a scale factor of 4.5 would be:

L = 8 × 4.5 = 36cm

W = 6 × 4.5 = 27cm

=>Area = L × B

= 36 × 27

Area = 972 cm²

=>Perimeter = 2(L + W)

= 2(36 + 27)

= 2(63)

Perimeter = 126 cm

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
