### Instruction: What is the area, in square units, of a triangle with vertices at $(0,0)$, $(0,5)$, and $(7,12)$? Express your answer as a decimal to the nearest tenth. Let's write a program.### Response: # to find the area of the triangle with vertices (x1, y1), (x2, y2) and (x3, y3)
# we can use the formula: 1/2 * abs(x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2))

# define the coordinates of the vertices
x1, y1 = 0, 0
x2, y2 = 0, 5
x3, y3 = 7, 12

# calculate the area of the triangle
area = 0.5 * abs(x1*(y2 - y3) + x2*(y3 - y1) + x3*(y1 - y2))

# round the area to the nearest tenth and print the result
print(round(area, 1))
