Answer:
(2x^2 -x) is the correct answer....
Explanation:
The formula to find area of triangle=1/2× base × height
Now , 1/2[2x(2x-1)]
1/2[2(2x^2-x)]
(2x^2- x)
So ,the area of triangle is = (2x^2 -x)
Hope it helps you

Answer:
Base= 2(2x+3)
=4x+6
Height= 2x-3
Hence, area= 1/2bh
=1/2×(4x+6)×(2x-3)
=1/2×(8x²-12x+12x-18
=1/2(8x²-18)
1/2(8x²-18)=0
8x²-18=0
8x²=18
x²=18/8
=9/4
x=√9/√4
=±3/4
