The equation P= 21 + 2w models the perimeter, P, of a rectangle with a length of / units and a width of w units.

natima [27]

Answer:

width = 10 units and length = 20 units

Step-by-step explanation:

Let the width be w

so Length will be 2w

using the rectangle formula:

$\sf Perimeter \ of \ rectangle= 2L + 2W$

$\sf 60= 2(2w) + 2w$

$\sf 60= 4w + 2w$

$\sf 60= 6w$

$\sf w = 10 \ units$

Find length:

$\sf length = 2w$

$\sf length = 2(10)$

$\sf length = 20 \ units$

Liliana wants to determine the height of an enlarged photo that she plans to frame. The original photo was 11 inches wide by 14

vova2212 [387]

For this case, the first thing we must do is find the scale factor.

For this, we use one of the dimensions. We will use the width of the photo.

We have then:

$k = \frac {132} {11}\\k = 12$

Then, we look for the value of the height of the new photo. To do this, we multiply the scale factor by the original dimension.

We have then:

$14k = 14 (12) = 168$

Answer:

the new height will be:

d.168 inches
