उत्तर


Let A be the required area.

Given equation of curve 2x + 4y = 10

i.e., x = 5 – 2y

∴ A = `int_2^(5/2) x  "d"y`

= `int_2^(5/2) (5 - 2)  "d"y`

= `[5y - (2y^2)/2]_2^(5/2)`

= `[5y - y^2]_2^(5/2)`

= `[5(5/2) - (5/2)^2] - [5(2) - (2)^2]`

= `25/2 - 25/4 - (10 - 5)`

= `25/2 - 6`

= `1/4` sq.units
