Answer:
192 = (x^2 + 8x)/2
Step-by-step explanation:
we know the base is x and the height is x+8.
Area of the triangle is 1/2 bh.
we know h and x
if we take area to be 192, we can write the area to be;
1/2 x(x+8) =A
The area of rectangular is A= length x width
120 feet of fancing = ---------------------------------- (the above line)
!-----------------------------------------!
! !
x ! the enclosed area ! x
! !
!---------------------------------------- !
120 -(x+x)
so the area is A = (120-2x) (x)= 120x-2x²
