Answer:
The area of the triangle is basically half the area of the square, so we only need to find the area of the square and divide it by 2:
S = (15 · 15)/2 = 112.5 (square units)
112.5 square units
Step-by-step explanation:
Area = 1/2bh
where b = 15 and h = 15 (you can look at the graph)
So A = 1/2(15)(15) = 225/2 = 112.5 square units
