1.

The area of the region enclosed by the curves `y""=""x ,""x""=""e ,""y""=1/x`and thepositive x-axis is(1) `1/2`squareunits(2) 1 square units(3) `3/2`squareunits(4) `5/2`square units

Answer» area of 1 = `1/2 xx 1 xx 1 = 1/2`
area of 2 = `int x dx = int y dx`
`int_1^e 1/x dx`
`= ln x`
`= ln e = 1`
total area =`1/2 + 1 = 3/2 unit^2`
option 3 is correct
