Answer:
9 yards
Step-by-step explanation:
Let the length of each quilt be 'l'.
Given:
Length of green felt (g) = 15 yards
Length of blue felt (b) = 12 yards
Total number of quilts = 3
Now, the length of 3 quilts is given as:
[tex]Total\ length=l+l+l=3l[/tex] ----- (1)
As per question:
Total length = Length of green felt + Length of blue felt
Total length = [tex]g+b[/tex]
[tex]Total\ length=15+12=27[/tex]--------- (2)
Now, comparing equations (1) and (2), we get:
[tex]3l=27\\\\l=\frac{27}{3}\\\\l=9\ yards[/tex]
Hence, each quilt measures 9 yards in length.
