The answer is: 3 3/8 sq ft so C
Given:
Two planks are each 1.5 m long.
One plank is 2.5m long.
To find:
The total length of all the three planks.
Solution:
Two planks are each 1.5 m long. So,
First plank = 1.5 m
Second plank = 1.5 m
One plank is 2.5m long. So,
Third plank = 2.5 m
Now, the total length of all the three planks is
Therefore, the total length of all the three planks is 5.5 m.
You can use trigonometry and the tangent to get:
tan(11°)=150/x
so x=772 ft
