Answer:
333
Step-by-step explanation:
The area of the square is 81 bc 9x9 = 81,
the formula for a triangle is base x height divided by 1/2
the base 9 x height 14 = 126 then divide by 1/2(or 2) to get 63, because all 4 triangles are congruent do 63 x 4 to get the answer of all 4 triangles which is 252.
Then add the area of the square to the area of the 4 triangles, 81 + 252 = 333
