Question

Hand made the drawling of his bedroom. The bedroom was measures 3.25 inches by 4.75 inches on the drawing. What's is the perimeter of his actual bedroom if the drawling has a scale of 1 inch: 4 feet?

Answer 1

Let's firstly calculate the perimeter of the drawing of the bedroom.

`\text{perimeter(drawing) P}=2(l+b)`

Given;

`\begin{gathered} l=3.25\text{ inches} \\ b=4.75\text{ inches} \end{gathered}`

So, the perimeter of the drawing is;

`\begin{gathered} P=2(3.25+4.75) \\ P=2(8) \\ P=16\text{ inches} \end{gathered}`
