The width of the deck will be 9 inches when the length of the deck is 12 inches.
In the drawing, the dimensions of the deck is:
Length = 8 inches
Breadth = 6 inches
The deck's dimensions is:
Length = 12 feet
We need to find the width of the deck
For this, we will use the ratio
Let the width of the deck be x
8 : 12 = 6 : x
8 / 12 = 6 / x
Cross multiplying the numbers, we get that:
8 x = 72
x = 72 / 8
x = 9
Therefore, the width of the deck will be 9 inches when the length of the deck is 12 inches.
