Answer:
448 ft^2
Step-by-step explanation:
The area of the walls is the perimeter of the room multiplied by the height.
P = 2(L + W)
P = 2(13 ft + 15 ft)
P = 2(28 ft)
P = 56 ft
A = perimeter * height
A = 56 ft * 8 ft
A = 448 ft^2
The coefficient of x is the value for slope in y-intercept form, and the number that we add or subtract is our y-intercept. So in this case, we want to look for a "-2" in front of x and a +4 in the equation.
Answer choice A fulfills those conditions. (I am also assuming that answer choice A should have had an x in it, but you accidentally forgot to type it.)

Answer:
length of the prism = 244 - (width x height) / width + height)
Step-by-step explanation:
Let length be a and width be b and height be c
2 (a * b) + 2 (b* c) + 2 (a * c) = 488
2ab+ 2bc + 2ac = 488
ab + bc + ac = 244
ab + ac = 244 - ac
a (b + c) = 244-ac
a = 244-bc / b + c
Therefore the length of the prism = 244 - (width x height) / width + height)
