Lester measured a picnic area near the river and made a scale drawing. The scale of the
drawing was 1 inch : 2 yards. The picnic area is 49 inches in the drawing. How wide is the
actual picnic area?
yards

Answer 1

1 inch : 2 yards can be written as 1 over 2. Then we write 49 (inches) over x, the number of yards we don’t know. Then we cross-multiply.

1/2 = 49/x
x = 49 • 2
x = 98 yards
