Hello guys. I need some help with 3 problems and a double check on 2 problems.

For the trapezoid it is isosceles and the perimeter is 32. How do I find the hegiht to find the area? For some reason I keep on getting 2.5 for the height and it's wrong.
Now the second image with the square I am totally clueless on how to get started with that one... If someone can walk me through it that would be great.
Finally the third one is a 12 by 16 feet rectangular floor that will be covered by square tiles that are 2 feet on each side. If the tiles are not cut, how many of them will be needed to cover the floor? For this one I got 96, but it's not the right answer...
Now for double checking.
There are two similar trapezoids the small one has a base of 24 and an area of 558 the large trapezoid has a base of 57 what is the area? I got 1325.
There are two similar triangles the large triangle side length measure 40 with an area of 1589 the smaller triangle has a side length of 35 what is the area? I got 1390 for this.
Thanks for your guys help!
