Answer:
1/2
Step-by-step explanation:
Anything with an exponent of 1 is itself.
You have to multiply each side by 2.5 then multiply the two new sides to get the answer. So 8 1/2, which is 8.5 is going to become 21.25 and 11*2.5 is going to become 27.50. So the new dimensions are 21.25 and 27.50, you multiply both of them which would give you an area of 584.375. YOU'RE WELCOME :)
