Question

5 In a scale drawing of a rectangularroom the scale is 1 inch: 4.5 feet. Findthe perimeter and area of the room.2 in5 in.

Answer 1

For this case the perimeter is given by:

P= 2*2 + 2*5 in = 4 +10 = 14in

And the real value would be:

`14in\cdot(4.5ft)/(1in)=63ft`

And the area can be founded on this way:

`A=(2\cdot4.5)\cdot(5\cdot4.5)=202.5ft^2`
