Answer:
A would be equivalent
Step-by-step explanation:
if you think about it answers c and d would not make sense because they use 14 and not nine, so if you comapare the two you should get answer A
Assume w is the width. the length is 3*2w
To fence the whole outside of farm, he needs:
2(w+6w)=14w meters
Also he needs one width and one length for the enclosed pens. Therefore, the total amount of fencing he would need:
14w+w+6w=21w meters
I find it easier to have a visual for when solving for shapes. You should solve for area of the semicircles by doing A=(3.14r^2)/2
Radius in this case is the base /2
In a Calculator that can be inputted as (3.14(4))/2
for this problem though I'm afraid that I need to know whether the height belongs to the figure as a whole or just regarding the rectangle.
If it is just the rectangle then we can do A=B*h
A= 4*5= 20
20 + semicircle
20 + 6.28
Total= 26.28
