Length(l)= 2w
Width(w)= w
Area(A) = l*w
A= 128 ft²
128= l*w
128= (2w)w
2w²= 128
w²= 64
w=√64= 8 ft
w= 8 ft
length(l)= 2w
l=2(8)
l=16 ft
P= 2l+2w
P=2(16)+2(8)= 32+16= 48ft
P= 48ft
Answer:
The Perimeter of this rectangle is 48 feet.

Hi there.
Since she reads 15 pages in 2 hours, all we have to do to find out how much she reads in 1 hour is divide.
15/2 = 7.5
7.5 pages/hour
Same applies to the pay
40/2 = 20
$20/hour
Karyn proofreading rate is 7.5 pages per hour. Karyn receives on average $20 per hour.

A. is 1/4 so that would be 25%
sorry thats all i know
We see that the area is 159 3/8 and the length is 18 3/4.
Because the area is the length*width, to find the width, we must divide the area by the length.
Think of it this way:

Divide l on both sides:

And w is what we're looking for.
So, divide 159 3/8 by 18 3/4.
You should get that the width is 8.5 feet :)
The area model you can use is D , cs 70 +3 & 30+9
