Question

A square playground has sides that each measure 120 feet in length.On a scale drawing, 1/4 inch represents 5 feet on the playground. How long is a side of this playground on the scale drawing?

a 6 inch

b 20 inch

c 24 inch

d 25 inch

e 30 inch

Answer 1

Set up a proportion

0.25 inch = x inch

------------- ----------

5 feet 120 feet

cross multiplying (without dimensions)

120 * 0.25 = 5x

30 = 5x

6 = x

6 inches

Answer 2

Draw and label a diagram!

How many feet in each side of the square?

Divide that number by 5 and multiply by 1/4
