Answer:
30 inches
Step-by-step explanation:
1 inch : 3 yards means
1 inch in paper (drawing) is 3 yards in actual life
We can setup a simple ratio and solve this problem.
1 inch is 3 yards, so how many inch is 90 yards?
This is the question.
We set up 2 fractions (one for ratio and another for actual) and equate, cross multiply and solve:
The left side fraction would be the ratio, that is:
1/3
THe right side fraction would be the actual, that is:
x inches (let it be x, we want to find x)
90 yards
SO we can write and solve:
[tex]\frac{1}{3}=\frac{x}{90}\\3x=90*1\\3x=90\\x=\frac{90}{3}\\x=30[/tex]
Hence,
The field is 30 inches in the drawing
