Answer:
Perimeter = 28.8 inch
Step-by-step explanation:
Step 1: Change given centimeters into inches according to the scale
2.5 / .5 = 5 <--- length in inches
4.7 / .5 = 9.4 <--- width in inches
^^^This is the same thing as multiplying 2.5 cm and 4.7 cm by two. You could also reword the scale to be 1 cm = 2 inch if it makes more sense for you
Step 2: Find the perimeter using the formula: P = 2L + 2W
2 (5) + 2(9.4)
10 + 18.8
