Solution

Let A be the required area.

Given equation of the curve is y = `sqrt(2x + 3)`

∴ A = `int_0^2 y  "d"x`

= `int_0^2 sqrt(2x + 3)  "d"x`

= `int_0^2 (2x + 3)^(1/2)  "d"x`

= `[((2x + 3)^(3/2))/(3/2) xx 1/2]_0^2`

= `1/3[(2x + 3)^(3/2)]_0^2`

= `1/3[(4 + 3)^(5/2) - (0 + 3)^(3/2)]`

= `1/3[(7)^(3/2) - (3)^(3/2)]`

∴ A = `1/3(7sqrt(7) - 3sqrt(3))` sq.units
