Find the area and perimeter of a rectangle that has a length of (x + 24) and (x + 16). Show all work for full credit.

klio [65]

Answer:

Perimeter of rectangle = 4x + 80

Area = x² + 40x + 384

Step-by-step explanation:

Perimeter of rectangle = 2*(length + width)

= 2* (x + 24 + x + 16)

= 2*( x +x + 24 + 16) {Combine like terms}

= 2* (2x + 40)

Use Distributive property : a*(b +c) = a *b + a*c

= 2*2x + 2*40

= 4x + 80

Area of rectangle = length * width

= (x + 24) (x + 16) {use FOIL method}

= x*x + x*16 + 24*x + 24*16

= x² + 16x + 24x + 384 {Combine like terms}

= x² + 40x + 384

For this case, what we must do is find the scale factor.
We have then that the scale factor is given by:
$k = \frac{L1}{L2}$
Where,
L1: side length of polygon ABCD
L2: side length of polygon PQRS
Note: both sides belong to the same side of each polygon
Substituting the values we have:
$k = \frac{6}{12}$
Rewriting we have:
$k = \frac{1}{2}$
Answer:
The scale factor of dilation is given by:
$k = \frac{1}{2}$
