Respuesta :

Answer:

1. 27 units

2. 31.5

Step-by-step explanation:

The computation is shown below:

1. For the perimeter

first we have to determine the new length and new width

New length = 1.5 × 7 = 10.5

ANd, the new width is = 1.5 × 2 = 3

Now the perimeter is

= 2 (l +w)

= 2 (10.5 + 3)

= 2 (13.5)

= 27 units

2. Now the area of new rectangle is

= length × width  

= 10.5 × 3

= 31.5
