HEy, dont every do tht
Step-by-step explanation:
Answer: The quadrilateral used here is a trapezium.
For this case we have that by definition, the perimeter of the rectangle is given by:
![P = 2w + 2L](https://tex.z-dn.net/?f=P%20%3D%202w%20%2B%202L)
Where:
W: Is the width of the rectangle
L: is the length of the rectangle
According to the data we have:
![L = 6 + w\\P = 48](https://tex.z-dn.net/?f=L%20%3D%206%20%2B%20w%5C%5CP%20%3D%2048)
Substituting:
![48 = 2w + 2 (6 + w)\\48 = 2w + 12 + 2w\\48 = 4w + 12\\48-12 = 4w\\36 = 4w\\w = \frac {36} {4}\\w = 9](https://tex.z-dn.net/?f=48%20%3D%202w%20%2B%202%20%286%20%2B%20w%29%5C%5C48%20%3D%202w%20%2B%2012%20%2B%202w%5C%5C48%20%3D%204w%20%2B%2012%5C%5C48-12%20%3D%204w%5C%5C36%20%3D%204w%5C%5Cw%20%3D%20%5Cfrac%20%7B36%7D%20%7B4%7D%5C%5Cw%20%3D%209)
So, the width of the rectangle is 9 inches
![L = 6 + 9 = 15](https://tex.z-dn.net/?f=L%20%3D%206%20%2B%209%20%3D%2015)
So, the length of the rectangle is 15 inches
Answer:
the width of the rectangle is 9 inches
the length of the rectangle is 15 inches
.87 is correct you can always check your work with an online calculator. :)
Yes this is correct because that angle in is with the other angles to
