I got 198in^2 because I broke the figure up into a triangle and a rectangle. then I thought of how much it would take for 13in to be congruent to 17in (which is 4). So I found that and I multiplied it by 7 to get the area of the triangle (28). And then to find the rectangle I multiplied 17×10 to get 170 and added 170+28 and got 198in^2
Answer:
Sean got 63/81 questions right as a fraction.
Step-by-step explanation:
Sean got 63/81 correct. If there was a total of 81 questions, you put that as your denominator.
Now ask yourself: Can you simplify?
Yes you can.
You divide each number from the fraction by 9.
63 / 9 = 7
81 / 9 = 9
7/9 questions that Sean got correct.
