A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7.
loris [4]

Answer:

New\ Lengths = (14,21)

New\ Scale\ Factor = \frac{1}{7}

Step-by-step explanation:

Given

Rectangle:

Length = 2 in

Width = 3 in

Scale Factor = 7

Solving (a):

The side lengths of the new scale is calculated as follows;

New Lengths = Old Lengths * Scale Factor

New\ Lengths = (2,3) * 7

New\ Lengths = (2 * 7,3* 7)

New\ Lengths = (14,21)

Solving (b): To go back to the original length

Given that the initial scale factor is 7;

The new scale factor is the reciprocal of the old factor;

Hence;

New\ Scale\ Factor = \frac{1}{7}
