Answer:
76 cm
Step-by-step explanation:
P=2L+2w
324=2(86)+2w
324=172+2w
324-172=2w
2w=152
w=152/2
w=76 cm
Let x be the <span>heights of a maple tree and y be the height of the cherry tree.
We know:
</span>
![\frac{x}{y} = \frac{5}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7By%7D%20%3D%20%5Cfrac%7B5%7D%7B2%7D%20)
<span>The new ratio is obtained like this:
</span>
![\frac{x+20}{y-20} = \frac{3}{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%2B20%7D%7By-20%7D%20%3D%20%5Cfrac%7B3%7D%7B1%7D%20)
.
From the above equation we get
![x= (y-20)\frac{3}{1} -20](https://tex.z-dn.net/?f=%20x%3D%20%28y-20%29%5Cfrac%7B3%7D%7B1%7D%20-20)
.
then
![\frac{ (y-20)\frac{3}{1} -20}{y} = \frac{5}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%28y-20%29%5Cfrac%7B3%7D%7B1%7D%20-20%7D%7By%7D%20%3D%20%5Cfrac%7B5%7D%7B2%7D%20)
Solving the above equation for y we get:
![y=160](https://tex.z-dn.net/?f=y%3D160)
So
So the first tree is (400-160=240) more taller than cherry tree.
