Question

On a scale drawing of a house, a rectangular bedroom has a length of 8 inches and a perimeter of 30 inches. The scale is 0.5 inch = 1 foot.

What is the actual width in feet of the bedroom?

Answer 1

2L + 2W = perimeter = 30
L+W = 15
If L = 8 , then W = 7
but .5 inches ---> 1 foot or 1 inch ---> 2 feet

so 8 inches ----> .... feet
and 7 inches ---> .... feet

Answer 2

I don't get it?
