Answer: B, 70 inches.
Explanation:
Let's start slow and go shape by shape.
Based on the information we have, we know that the length for the rectangle is 8 inches by 7 inches. 8*7 = 56, so we have one of the answers.
Next, we do the triangle. Based on the information we have, we know that the triangle is 4 inches by 7 inches divided by 2. 4*7 = 28
![\frac {28}{2} = 14](https://img.qammunity.org/2020/formulas/mathematics/middle-school/4sdzp8qurkksawlfxt0tosjvljk1lxgfar.png)
