Area inside the parabola

y^2=4 a x

, between the lines

x=a

and

x=4 a

is equal to

View answer and explanation

Correct option: C

28 \frac{a^2}{3}

Option C (

28 \frac{a^2}{3}

) is correct because the area inside the parabola

y^2=4ax

between the lines

x=a

and

x=4a

is found by integrating

2\sqrt{ax}

from

a

4a

, which results in

\frac{28}{3}a^2
