Answer:
gonna solve fore perimeter and area
P = 12 + 3 + 3 + 9 + 9 + 4 + 4 + 4 = 48cm
P = 48 cm
For area or A it is
A = (12*3) + (4*9) = 72 cm^2
Step-by-step explanation:
use deductive reasoning to determine the missing side lengths, and then solve by splitting the figuring into multiple rectangles
Attached is a picture of my answers.
The answer is 54 dollars I believe
So if 6 out of 40 are incorrect, 40-6= 36 must be correct.
In order to gain percentage you do proportions.
36/40 = x/100.
Multiply 36 times 100 then divide by 40, which is 90.
The answer is 90%.
90% of the questions he got were correct.
