Question

Area bounded by lines $y = 2 + x$ $y = 2 - x$ and $x = 2$ is

• A. 3
• B. 4
• C. 8
• D. 16

Answer 1

Answer: (B)

4

Answer 2

Obviously, triangle ACB is right angled at C.

∴ Required area $= \frac { 1 } { 2 } \times A C \times B C$

$= \frac { 1 } { 2 } \times 2 \sqrt { 2 } \times 2 \sqrt { 2 } = 4$ sq. unit.
