We have been given the measure of two parallel sides as 11 m and 5 m. And we are given one of the slanted sides as 4 m.
From the given information, we can find the base of one of the side triangles as 3 m.
Therefore, upon using Pythagorean theorem, we get the set up for height as
![h^(2)=4^(2)-3^(2)=7](https://img.qammunity.org/2019/formulas/mathematics/middle-school/bgnakn75wefo92o4ygzvxddqfce6a8nmgm.png)
![h=√(7)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/v469gxugmcr8z8xcpmwre13cewbxrbne36.png)
Therefore, height of the required figure is
m
