Question

In the figure, the shaded part is bounded by the axis the lines x=3 and x+y=5 which is the area of the shaded region....
Here is your options:
a)10.5
b)12
c)15
d)19.5​

Answer 1

Answer:

..........

.

10.5= 3*(5+2)/2

Answer 2

Answer : 10.5

To find the point of intersection,

solve the equation $\left \{ {{x=3} \atop {x+y=5}} \right.$

The solution is $(x,y)=(3,2)$ and it is the intersection

The trapezoid comprises (0,5),(0,0),(3,0),(3,2)

The two parallel lines are having length 5 and 2

The height is 3

The shaded area is 21/2 or 10.5
