Answer:
D. 850 square foot
Step-by-step explanation:
Area of a space is the length
multiply by the width
The area for the kitchen, dining, office and sunroom will be calculated independently and added together.
Note the word "and the office and sunroom are each 10 feet by 10 feet"
Kitchen area = 10 ft x 15ft= 150sqft
Living/Dining area = 20ftx25ft= 500sqft
Sunroom = 10ftx10ft= 100sqft
Office= 10ftx10ft=100sqft
Therefore total surface area is the cumulative of the 4 areas
150sqft+500sqft+100sqft+100sqft= 850sqft

Answer: 82</h3>
====================================================
Explanation:
Let A be the tens digit and B be the units digit
We can write the number as AB. So if A = 9 and B = 2 for instance, then the number is AB = 92. Keep in mind I'm not multiplying A and B here.
"The unit digit is a prime" means B could be any of these values {2,3,5,7}. We only list the single digit primes. The value 1 is not prime.
Now multiply each of those items by 4
4*2 = 8
4*3 = 12
4*5 = 20
4*7 = 28
Of those results, only 4*2 = 8 leads to a single digit answer.
This must mean that A = 8 and B = 2
Therefore the number is AB = 82.
