Answer:
width = 23 inches
length = 57 inches
Step-by-step explanation:
Let x inches be the width of the rectangular solar panel.
So,
width = x inches
3 times the width = 3x inches
12 inches shorter than 3 times the width = 3x - 12 inches
length = 3x - 12 inches
The perimeter of the rectangle is
Hence,

the answer is B. Subtract the total for the turkey from the beef.
To answer this you will use the formula for finding area of a parallelogram.
A = bh
3 inches x 2 inches
A = 6 square inches per piece of paper
6 square inches x 15 = 90 square inches
90 in.² of paper is used to make 15 pieces.
