Answer:
Area of rectangular bedroom = 3000 square feet
Step-by-step explanation:
It is given that the total distance around the rectangular bedroom is 220 feet
perimeter of rectangle = total distance around the rectangle
hence the perimeter of rectangle = 220 feet
now width of rectangle = 50 feet
Let us assume the length of rectangular room be L
we have formula

now we plug perimeter = 220 and width = 50
so we have
(divide both side by 2)
(subtract 50 from both side )
Area of rectangular bedroom is given by
Area = length × width
Area = 60 × 50
Area = 3000 square feet
Answer:
Step-by-step explanation: 6z=-2-10
6z= -12
z=-12/6
then z= -2

Just find out the work cause im not goin to put it
Let x = one of the side lengths of the base.
Then area of the base = x². So volume of the base = x²h.
That gives us x²h = 20. Solving for x, we get x = √(20/h²).
Glass is needed to cover the sides of the aquarium. There are 4 sides and 1 base. Area of a side = hx = h√(20/h²). Area of the base = x² = 20/h. Total area of glass = h√(20/h²) + 20/h. So the cost for glass = 8 * [h√(20/h²) + 20/h] = 8 h√(20/h²) + 160/h.
Metal frame is needed along the edges of the sides. There are 4 edges on the top, 4 edges in the bottom and 4 vertical edges. So the total length of metal frame = 4x + 4x + 4h = 8 √(20/h²) + 4h. Then the cost for metal frame = 7 * [8 √(20/h²) + 4h] = 56 √(20/h²) + 28h.
So the total cost = 8 h√(20/h²) + 160/h + 56 √(20/h²) + 28h
