Just in case you can't see h = 1.8ft left side 3.3 right side 2.2 and bottom 4. can somebody plz find the answer and explain how to find it?

To find the area, you have to split the triangle into two right triangles.

Then, use the Pythagorean Theorem to find the missing side length on the bottom.

For the left triangle,





For the right triangle, 





Using these, we can determine area of both triangles and add them together to get the total area of the triangle.

Left triangle's area = 



Right triangle's area =



Total area = 
Left + Right = 3.627 ft^2

To get perimeter, just add all of the original side lengths, except height, together.

3.3 ft + 2.2 ft + 4ft = 9.5 ft

Hope this helps!
