Reread, take time, and concentrate
Johnny must get a test grade of a 96.
That is because adding 92 to 96 would give him 188
92 + 96 = 188
You would need to divide by 2 to find the averages of the test
188/2 = 94

Answer: 122 sq. in.
Step-by-step explanation:
P = 2 (l + w)
P = 2 (34.5 + 26.5)
P = 2 x 61
P = 122 sq. in. = 0.847 sq ft = 0.0941 sq. yards
I think it’s 1 feet because the tops are touching you have to spread the bottoms apart so it can touch
The answer is 0.5
Have an nice day!
