Answer:
The actual wide of the lawn is 24 meters
Step-by-step explanation:
we know that
The scale drawing is

using proportion
Find out how wide is the actual lawn if the lawn is 48 millimeters in the drawing
Let
x -----> the actual wide of the lawn

therefore
The actual wide of the lawn is 24 meters
The area would be 30. it would be 6x5
Parallelogram area = base * height
30 = 10 * height
height = 3
Sine Parallelogram Angle = height / side
Sine (Angle) = 3 / 6
Sine Angle = .5
Angle = 30 degrees
