If we know that the sum of the two right sides of a right triangle is equal to 8 and what are the two right sides, what is the maximum area of the right triangle? This is a function problem. Let's set X

If we know that the sum of the two right sides of a right triangle is equal to 8 and what are the two right sides, what is the maximum area of the right triangle? This is a function problem. Let's set X

Let a right edge be x and its area be y
y=0.5x(8—x)
Sorting: y = - 0.5x2 + 4x
Change to vertex formula: y = - 0.5 (x-4) 2 + 8
Because - 0.5
