**14. IPMAT (I) 2019 QA MCQ | Coordinate Geometry**

The area enclosed by the curve 2|x| + 3|y| = 6 is

- A.
12 sq. units

- B.
3 sq. units

- C.
4 sq. units

- D.
24 sq. units

Answer: Option A

**Explanation** :

2|x| + 3|y| = 6

**Case 1**: x > 0 and y > 0 [Quandrant I]

⇒ 2x + 3y = 6

**Case 2**: x < 0 and y > 0 [Quandrant II]

⇒ - 2x + 3y = 6

**Case 3**: x < 0 and y < 0 [Quandrant III]

⇒ - 2x - 3y = 6

**Case 4**: x > 0 and y < 0 [Quandrant IV]

⇒ 2x - 3y = 6

Each of these 4 lines can be drawn in their respective quadrants as shown in the figure.

Area of region I = 1/2 × 3 × 2 = 3 sq. units

Similarly area of region II, III and IV = 3 sq. units each.

∴ Area of all the 4 regions combined = 3 + 3 + 3 + 3 = 12 sq. units

Hence, option (a).
