Step-by-step explanation:
We have given that 4 boards are of
so total number of feet of 4 boards =
![4* (117)/(8)=58.5feet](https://img.qammunity.org/2020/formulas/physics/high-school/28z4yn71konn7lfq2cuusiwaxji081s2yi.png)
Two board are of
so total number of feet of two board
![=2* (47)/(4)=23.5feet](https://img.qammunity.org/2020/formulas/physics/high-school/t9izwg2coje789bqbhvcmzfune7j4bf7kq.png)
And two boards are of
so total feet
![2* (13)/(2)feet=13 feet](https://img.qammunity.org/2020/formulas/physics/high-school/80qavxe5bx9oyp0qtmd6188amum6xzv237.png)
So total height of all boards = 58.5+23.5+13=95 feet
