Draw the graphs of theequations┬аx┬а= 3,┬аx┬а= 5 and 2x┬атАУ┬аy┬атАУ4 = 0. Also find the area of the quadrilateral formed by the lines andthe┬аxтАУaxis.



Answer -

Solution:

Given equation oflines x = 3, x = 5 and 2x-y-4 = 0.

Table for line 2x тАУ yтАУ 4 = 0

x

0

2

y

-4

0

Plotting the graph, weget,

From the graph, weget,

AB = OB-OA = 5-3 = 2

AD = 2

BC = 6

Thus, quadrilateralABCD is a trapezium, then,

Area of QuadrileralABCD = ┬╜ ├Ч (distance between parallel lines) = ┬╜ ├Ч (AB) ├Ч (AD + BC)

= 8 sq units
