Correct option is (D) (3, 8)
The distance of point from Y-axis is x = 3 and the distance of point from X-axis is y = 8.
\(\therefore\) Point is (3, 8).
Correct option is (A) (5, 4)
x = Obscissa = Distance of point from Y-axis = 5,
y = Ordinate = Distance of point from X-axis = 4.
Thus, the point is (5, 4).
Correct option is (C) (-3, 6)
In \(Q_2\), x-coordinate is negative and y-coordinate is positive.
\(\because\) Distance of point from Y-axis = 3 units
\(\therefore\) Abscissa = -3 \((\because\) x-coordinate is negative)
\(\because\) Distance of point from X-axis = 6 units
\(\therefore\) Ordinate = 6
\(\therefore\) Required point...
Correct option is (C) 1
Area of flag \(=\frac12\times\) Base \(\times\) Height
\(=\frac12\times(2+\sqrt2)\times(2-\sqrt2)\)
\(=\frac{4-2}2\) = 1 square units
