Find the area of quadrilateral formed by joining points (4,2), (8,2), (8,14) and (4,10). 

Area of the triangle formed by the graph of the straight lines x - y = 0, x + y = 2 and the x-axis is: 

The graphs of x = a and y = b intersect at 

The linear equation such that each point on its graph has an ordinate four times its abscissa is: 

If (2^x)(2^y) = 8 and (9^x)(3^y) = 81 , then ( x , y ) is : 

If a linear equation is of the form x = k, where k is a constant, then graph of the equation will be 

The graph of the equations 25x + 75y = 225 and x = 9 meet the point: 

The area bounded by the lines x = 0, y = 0, x + y = 1, 2x + 3y = 6 (in square units) is
