Question 63
The area of the quadrilateral bounded by the Y-axis, the line x = 5, and the lines $$\mid x-y\mid-\mid x-5\mid=2$$, is
Correct Answer: 45
Solution
From the inequality and nature of x, and y, we get the given diagram:
We need to find the area of the quadrilateral ABDE = area of rectangle ABCD + area of triangle CDE
=> Area of ABCD = (7-3)*5 = 20 units, and the area of triangle CDE = (1/2)*10*5 = 25 units.
Hence, the area of the quadrilateral ABDE = (20+25) = 45 units.
