12 units is not shaded in
Answer:
D)
Step-by-step explanation:
If the first rectangle has length, l, and width w then its perimeter is given by the following relation
2l+2w=72 divide by 2 on both sides so that the relation now becomes l+w=36
If l and w are scaled by a factor of 3.5, the new measurements of your resulting rectangle will 3.5l+3.5w-->3.5(l+w)
To answer this we need to divide 24 by 3/8.
First we need to convert 24 to a fraction.

When dividing fraction, multiply the first fraction by the reciprocal of the second fraction. (A reciprocal is an upside down fraction)

(simplify:) 64
