Answer:
225
Step-by-step explanation:
First, find the area of the sqare so 5x5 would be 25.
Next, find the area of the triangle, the formula for that is 1/2 base x height. Here the base is 5 in and the height is 20 so that would be (5 x 20) 1/2 which equals 50. Then, because there are 4 triangles multiply the fifty 4 times, 200.
Then take the 25 from the square and add it to the 200 to get your answer of 225!
