The area enclosed by 2|x| + 3|y| ≤ 6 is(a)  3 Sq-units(b)  12 Sq.units(c)  9 Sq.units(d)  24Sq.units 

Answer»

Correct option  (b) 12 Sq.units

Explanation:

2x + 3y ≤ 6, x ≥ 0, y ≥ 0

2x - 3y ≤ 6, x ≥ 0,  y ≤ 0

- 2x + 3y ≤ 6, x ≥ 0,  y ≤ 0

- 2x - 3y ≤ 6,  x ≤ 0, y ≤ 0

Form a rhombus with diagonals 4 & 6.

Area = 1/2 x 4 x 6 = 12 sq. units.
