Question

Juanita was asked to create a scale drawing of her bedroom. Using the dimensions and scale shown, determine the actual area of her room.

Answer 1

`\text{Actual area of room = 236.5 ft}^2`

Here, we want to get the actual area of the room

The shape is rectangular and the area of the shape is simply the product of the dimensions of its sides

Now, what we have to do here is to have the actual dimensions

That means we will multiply each of the dimensions in inch by 5 to get the dimensions in ft

Mathematically, we have this as;

`\begin{gathered} 2.2\text{ in }*\text{ 5 = 11 ft} \\ 4.3\text{ in }*\text{ 5 = 21.5 ft} \end{gathered}`

The actual area is thus the product of the actual dimensions above

We have the actual area as;

`11\text{ ft }*21.5ft=236.5ft^2`
