Area help with solution? Best answer 10 points

The area of rectangle bounded by the |x|=2, the x-axis and y=1 is?

Required area (A) = int(ydx, -2,2)
=int(1dx, -2,2)
=([x],-2,2)
=2-(-2)
=4 sq. units

|x|=2 x has values of -2 and 2 or x,y of (-2, +/- infinite) and (2, +/- infinite)
the difference between the points is 4

the differnce between lines bounded by x axis and y=1 is 1 so you have a rectangle 4 units in width and one unit high
the area is 4*1 or 4 units

Area rectangle = length*breadth= 1*4=4unit^2 (ANS)
