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
