Answer:
Therefore the dimensions of the garden is 16 feet by 13 feet.
Step-by-step explanation:
Let the length of the garden be x and the width of the garden be y.
Given that the area of the rectangular garden is 208 square feet.
Therefore,
xy =208
Again given that,
The garden is to be surrounded on three sides by a brick wall costing $ 8 per feet and the remaining sides by a fence costing $5 per feet.
The perimeter of the rectangle is = 2(length+ breadth)
= 2(x+y)
=2x+2y
The total cost of fence
= (16x+ 8y +5y)
To find the maximum or minimum point, we need to find out and set =0.
Then
Again
Therefore at x= 13 , the cost is minimum.
Therefore x = 13 feet.
The other side of the garden is feet = 16 feet.
Therefore the dimensions of the garden is 16 feet by 13 feet.
Answer:
about $2546.88
Step-by-step explanation:
You would multiply 15x20 to find the area, which is 300 sq ft. Then, you would find the cost per square foot by dividing 2275/300 which is 7.58 rounded to the nearest hundredth. Now that you have the cost per square foot, you find the area of 12x28 which is 336. Then, you just multiply 336(7.58) which is equal to $2546.88
