Answer:
height is 15
Y = L = Length
therefore 15y = (-x^2) +(300/20)
Step-by-step explanation:
15 = -x^2 +(300/20)
is the same as;
15 = (300/20) - (x^2)
we just add y to 15 and that can represent a division for x
y = L
Where area cm^2 can be shown as 300 as 15 x 20 = 300
when we divide by length we get the height as asked in the question.
