Answer:
A.
Step-by-step explanation:
We have, the dimensions of the living room are 30 ft and 20 ft.
Thus, area of the living room = length × width = 30 × 20 = 600 ft².
Now, it is given that the cabinet takes 6% of the living room i.e. 6% of 600 ft² = 0.06 × 600 = 36 ft².
As, the triangle has dimensions (2x+3) ft and (3x+6) ft.
So, the area of the triangle =
i.e. Area of cabinet =
i.e. Area of cabinet =
i.e. Area of cabinet =
Since, the cabinet takes 6% of the living room, we have,
= 36
i.e.
i.e.
i.e.
Further, as the solution of a quadratic equation is given by
On comparing we have, a=2, b=7, c= -18.
Thus,
i.e.
i.e.
i.e. and
So, according to the options, we have,
A. is the correct value of x.
