Answer:
364 square units
Explanation:
For this problem we can break the shape into a triangle and square then add them together to get the area. We know that the are of a square is side*side so we do 14*14 to get the area of that. Then we can do 1/2*base*height for the area of the triangle and we can use a side of the square as the base. We still need to find the height so we do pythagorean theorem using half the base and the 25 as the hypotenuse. So we do 25^2=7^2+Height^2 after rearranging we can do 25^2-7^2=Height^2 and find that the height is equal to 24. Then we simply plug in all the numbers like (1/2*14*24)+(14*14) to get 364
