Since the area of each square piece is 169 square inches, the length of each square is 13 inches!
Let:
L = Length
W = Width
The length is 7cm longer than its width, so:
The area is given by:
Therefore:
Solve for W using the quadratic formula:
Therefore:
W = 12.38238 since a negative width wouldn't make any sense
and:
Answer:
W = 12.38238 m
L = 19.38238 m
15/7 divides by 42/7 equals 357/1000 or .357
