Answer:
A = x(x − 4) − 0.5(8)(x − 4) − 3(7)
Step-by-step explanation:
x = length, making the width (x-4)
The stage closet will be (x-4)(8)(1/2)
The rectangle is 7(3)
That makes the painted area x(x-4) - 4(x-4)
So...
A = x(x − 4) − 0.5(8)(x − 4) − 3(7)
The printed area of the theater room is x(x − 4) − 0.5(8)(x − 4) − 3(7). Then the correct option is D.
What is Geometry?
It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 11 feet.
The width of the floor is 4 feet less than the length.
It will have a stage and a closet, and the remaining area of the floor will be painted.
Let, the length be x
Then the width will be (x - 4)
Then the stage closest will be
[tex]\dfrac{8(x- 4)}{2} \Rightarrow 4(x-4)[/tex]
The rectangle is 7(3)
The painted area will be given as
[tex]\rm x(x-4) - 4 (x-4)[/tex]
Then we have
[tex]\rm area = x(x - 4)- 0.5(8)(x - 4) - 3(7)[/tex]
