mathstudent55 · Answer

That's the area of the square garden of Hannah's husband.
If a square has 24.50 sq ft area, what is the measure of the side?

anonymous · Answer

6.125?

mathstudent55 · Answer

No.
When you had a side of 7, you squared it and got an area of 49.
Now you have an area of 24.5, so take the square root to get the side.
Take the square root of 24.5.

mathstudent55 · Answer

Scale problems can be solved with proportions.
Look at this table

Floor Plan    Real
1 in.            15 ft
3/4 in.         x
2/3 in.         y

mathstudent55 · Answer

You have a known ratio: 1 in. : 15 ft that is the scale
You want to know this ratio:  3/4 in. : x ft

1/15 = (3/4) / x
