Answer:
![\large\boxed{5\dfrac{1}{5}\ decimeters=52\ centimeters}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B5%5Cdfrac%7B1%7D%7B5%7D%5C%20decimeters%3D52%5C%20centimeters%7D)
Step-by-step explanation:
![1\ dm=10\ cm\qquad\text{(1 decimeters = 10 centimeters)}\\\\\text{Therefore}\\\\5\dfrac{1}{5}\ dm=\dfrac{5\cdot5+1}{5}\ dm=\dfrac{26}{5}\ dm=\dfrac{26}{5}\cdot10\ cm=\dfrac{260}{5}\ cm=52\ cm](https://tex.z-dn.net/?f=1%5C%20dm%3D10%5C%20cm%5Cqquad%5Ctext%7B%281%20decimeters%20%3D%2010%20centimeters%29%7D%5C%5C%5C%5C%5Ctext%7BTherefore%7D%5C%5C%5C%5C5%5Cdfrac%7B1%7D%7B5%7D%5C%20dm%3D%5Cdfrac%7B5%5Ccdot5%2B1%7D%7B5%7D%5C%20dm%3D%5Cdfrac%7B26%7D%7B5%7D%5C%20dm%3D%5Cdfrac%7B26%7D%7B5%7D%5Ccdot10%5C%20cm%3D%5Cdfrac%7B260%7D%7B5%7D%5C%20cm%3D52%5C%20cm)
Answer:
16.5+13.6+12.4.17.7= 60.2
60.2÷4 =15.05
L (length) = w+16
l x w = Area
260 = l x w
260 = (w+16) x w
260 = w^2 + 16w
w^2 + 16w -260 = 0
(w+26) (w-10) = 0
w= -26 (reject) or w = 10
if w = 10, l = 26
10ft x 16 ft
X=2t
y=1-t
t=x/2
y=1-x/2
y=(-1/2)x+1
