Answer:Gcf=1.
Step-by-step explanation: The factors of 2 are: 1, 2
.
The factors of 6 are: 1, 2, 3, 6
.
The factors of 15 are: 1, 3, 5, 15.
Suppose the length of the triangle is x, if the perimeter of the rectangle is 100 ft, the width of the rectangle will be (50-x) ft.
Area of rectangle will be:
A=length*width
A=x(50-x)
A=50x-x^2
at maximum area, dA/dx=0
thus
dA/dx=50-2x=0
solving for x we get
2x=50
x=25
thus for maximum area length=25 ft
the size of the width will be
50-x=50-25=25 ft
thus the maximum area will be:
25*25=625 sq. feet
Add the sides then what ever you got add that up with 9 yd
D would be the correct answer. Post brainliest if this helped plz :)
