Answer: It is proportional because 195/3 equals 65 and 325/5 equals 65 as well, so it is proportional.

Set up a ratio. But first convert the height of the puzzle to feet so we are comparing the same unit of measure.
STEP 1
convert 24 inches to feet
12 inches= 1 foot
24 inches= 2 feet
STEP 2
set up ratio.
= 2 feet/556 feet or 2:556
simplify both by 2
= 1 ft/278 ft or 1:278
ANSWER: 1/278 or 1:278 (can be written either way)

Answer:
area (A) =(9x+108)unit^2
perimeter (P) =(2x+42) units
Step-by-step explanation:
area(A) =length(l) × breadth(b)
perimeter(P) =2(l+ b) {which is sum of all sides}
so, l = 7+x+5 = (x+12) units and b = 9 units
now, A=(x+12) × 9 units^2
=(9×x + 12×9 ) units^2
Therefore,
A =(9x+108)unit^2
next, P=2{(x+12)+9}
=2(x+21)
Hence,
P=(2x+42) units
