2 * (7.5 * 5) + 2 * (2.3 * 5) + 2 * (2.3 * 7.5) =
75 + 23 + 17.25 =
115.25 cm²
Answer:
A
Step-by-step explanation:
Go to the graph at 12 weeks and the line for Baby A is above Baby B.
Area is the space inside a shape
So you would do 16 divided by 7 and it equals 2.285714285714286 and you would round to the nearest whole so the final answer would be 2 centimeters
The ratio is 3:2, purple :green
The bag has 21 purple so to get from 3 to 21 it is multiplied by 7; so we must also multiply the 2 by 7 to keep the ratio balanced.
21:14
