SATHEE: Area Question 53

Area Question 53

Question 53

Find the area bounded by the curve $x^{2} = 4 y$ and the straight line $x = 4 y - 2$ .

Show Answer

Solution:

The point of intersection of the curves $x^{2} = 4 y$ and $x = 4 y - 2$ could be sketched are $x = - 1$ and $x = 2$ .

$∴$ Required area

$\begin{aligned} = \int_{- 1}^{2} \frac{x + 2}{4} - \frac{x^{2}}{4} d x & = \frac{1}{4} \frac{x^{2}}{2} + 2 x - \frac{x^{3}}{3} & = \frac{1}{4} 2 + 4 - \frac{8}{3} - \frac{1}{2} - 2 + \frac{1}{3} & = \frac{1}{4} \frac{10}{3} - \frac{- 7}{6} = \frac{1}{4} \cdot \frac{9}{2} = \frac{9}{8} sq units \end{aligned}$
