First, you want to find the area of the entire thing first.
The length adds up to 14, the width to 10. Multiply and you get 140 as the total area.
Now to get rid of the flower bed is simple, 8 Multiply to 3 which makes 24, then divide by 2 which is 12. Substract 12 to 140 and you get 128.
The formula for a trapezoid is Area= (base1 +base2)/2 times height. Following this, and 5 and 7 which gets 12. divide 12 to 2 and you get 6. 6 times 10 is 60.
Subtract 60 to 128 and you get 68.
Mark best if possible please.
I believe the answer is 40%. I hope this helps!

Answer:
The percent error rounded to the nearest tenth is 8.6%.
Step-by-step explanation:
The general equation for percent error is as follows: percent error = [(experimental value - actual value) / actual value] x 100. In this problem, her experimental value, or the expected score was 85%. However, her actual score was 93%. When we subtract the two values, we get a difference of 8 and when we divide this number by the actual value of 93, we get a quotient of .086. Multiplying this answer by 100 will give a final percentage of 8.6%.
