Answer:
44.6
Step-by-step explanation:
Since the sides with the two tick marks are equal to 7.4, and there are three of these sides, they are equal to 7.4 times 3, which is 22.2. The remaining sides have 1 tick, meaning they are 11.2, meaning this is 11.2 * 2, which is 22.4. The combined perimeter is 44.6 cm.
Answer:
a. 10 + 2.50x
b. 60
c. 100
Step-by-step explanation:
