Step-by-step explanation:
Assuming that the patio is a rectangle, we have
Where is the length and
is the width.
Now let's assume that the length of the patio is double than the width.
So, the equation that represents this problem is
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:
----- (1)
As per question:
Total length = Length of green felt + Length of blue felt
Total length =
--------- (2)
Now, comparing equations (1) and (2), we get:
Hence, each quilt measures 9 yards in length.
A(b-c)=d solution is number 2. Attachment added
