Three and one hundred forty one hundredths <span />
I’m not sure if this is correct but
you have used 3/8 of the plants so you will have 5/8 left to use
It would be 24 units^2 because the middle is 16 and the two triangles are 4 each
Area of a Triangle = 1/2 * base * Height
2.5 = 1/2 * 2 * h
2.5 = 1 * h
h = 2.5 /1
h = 2.5 in
In short, Your Answer would be: Option C
Hope this helps!
