If the width of the field is 42 m and the length and width are in the ratio 5:3, then its length is:

🧠 Explanation:

If a field’s width is 42 m with a 5:3 length-to-width ratio, the length is 70 m. Solve: 3 parts = 42, so 1 part = 14, and 5 parts = 70. This teaches ratio calculations for geometry or real-world measurements.
