===============================
Problem: The ratio of the 4 sides of a quadrilateral is 2:4:5:7. How long was the longest side if the perimeter of the quadrilateral was 180 cm?
Solution: We need to multiply x, add each part of the ratio, and equate to 180.
- Substitute the value of x to the ratio.
- The shortest side is 20 cm, the shorter side is 40 cm, the longer is 50 cm, and the longest side is 70 cm.
- So according to the problem, find the longest side of the quadrilateral. Therefore, is the longest side of the quadrilateral.
