A rectangle is enlarged by a factor of 1.5. The width is given as w=2 and the length is given as l = 7 in. What would be the perimeter of the new rectangle?

Hence Perimeter for new rectangle will be 27 units.

Step-by-step explanation:

Given:

A rectangle with enlarged factor of 1.5

L=7 and W=2

To Find:

Perimeter for new rectangle

Solution:

First calculate the new dimensions for new rectangle,

Given that original length and width as 7 and 2 respectively and it is increasing by 1.5 times of the original ones

So

New length = 1.5 * L

=1.5 * 7

=10.5 units

And for width,

New width=1.5 * W

=1.5 * 2

=3

Hence New dimensions are 10.5 and 3 units.

So perimeter of new rectangle = 2 (New length + New breadth)

=2 (10.5+3)

=2 (13.5)

=27 units
