Let's define variables:
w: width of the photograph
l: length of the photograph
The cost of the box is:
2 * (2 * (w + 2)) + 2 * (2 * (l + 2)) = 160
The area is:
(w + 2) * (l + 2) = 231
Solving the system of equations we have:
w = 5 inches
l = 31 inches
Then, the dimensions of the frame are:
w + 2 = 7 inches
l + 2 = 33 inches
Answer:
the dimensions of the frame are:
7 inches * 33 inches
Answer:
Step-by-step explanation:
<em>See the attached.</em>
The path goes along the perimeter of the park and parallel to the sides, something like the picture attached.
<u>The path is 1 m wide and the total length is:</u>
We need to consider the dark cells points in the picture with reflects the overlaps. They are counted twice and each is 1 m x 1 m.
<u>Subtracting the duplicated area 9 x 1 m² to get the total area of the path:</u>
<u>The cost of cementing is:</u>
The factors is 5,4,3,6,12
