i BELIEVE it is 225. you have to look at it in different shapes. thats basically a rectangle and a triangle. the formula for a square is base times height but im sure you know that. you use the same formula for a triangle but divide it by two. so for this, you have 14 feet to the highest point, and 4' on the other side until the diagonal point starts, so you know where the rectangle ends, and the triangle begins on the side that is 14 feet. which is 4 feet leaving you 10 for the triangle, and 4' for the rectangle. we already know the base because its given, which is 25' for the base. and the rectangle is left to 25'x4'. so for the triangle, it becomes 10'x25' which is 250, divided by 2 is 125 for the area of the triangle. that leaves 25'x4' for the rectangle which is 100sq ft. add the two and its 225.
maybe im wrong, its been a while since i did this crap.
Think we all might be missing something here. Apparently this shape does not have two 90 degree angles. If one side of the triangle is 10, and the other is 25, the hypotenuse cannot be 30 if this is a right triangle!
Good attn to detail. That would make the shape four-sided polygon. or a Quadrilateral. Not sure without checking but I think you would avg. the base times the avg of the height.
25+30= 55 / 2 =27.5
14+4 = 18 / 2 = 9
