To solve this problem you must follow the proccedure shown below:
1. You have that <span>the pasture must contain 128 square meters and no fencing is required along the river. Then:
A=LxW
A is the area
L is the lenght
W is the width
2. Let's clear W:
W=A/L
W=128/L
3. The formula of the perimeter is:
P=2L+W
P=2L+(128/L)
4. Now, you must derivate:
dP/dL=0
2+(128/L</span>²)=0
<span> L=8 meters
W=A/L
W=128/8
W=16 meters
</span>
4x-8= -32
A chart to help with this is
+ x + = +
+ x - = -
- x - = +
4.5/3= 1.5
It is 1.5 times bigger than the smaller triangle.
So,
5*1.5= 7.5
x= 7.5
I hope this helps!
