The formula for perimeter is 2L + 2W.
Since we know that L=5+W, we can substitute this into the equation.
2(5+W) + 2W=58
10+2W+2W=58
4W + 10=58
4W=48
W=12
Therefore, the width is 12 inches.
The width of the rectangle is 12 inches if the flat rectangular piece of aluminum has a perimeter of 58 inches.
What is a rectangle?
It is defined as the two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
We have:
A flat rectangular piece of aluminum has a perimeter of 58 inches.
Perimeter = 58 inches
2(l + w) = 58
l = 5 + w
2(5 + w + w) = 58
10 + 4w = 58
4w = 48
w = 12 inches
Thus, the width of the rectangle is 12 inches if the flat rectangular piece of aluminum has a perimeter of 58 inches.
