The area enclosed by the figure represented by the system of inequalities x ≥ -5, y ≤ 3, x ≤ 0, y ≥ 0 is
15 sq. units
12 sq. units
30 sq. units
15/2 sq. units
The required region is a rectangle given by ABCD and hence the area is 15 sq. units.
The solution set of the system of inequalities given by 7y – 3x ≥ 21, x + y ≥ 1 and y ≤ 0 is
