Answer: 123 square feet
Step-by-step explanation: The question is a little odd, but I can break it down easily. It wants us to find the area of a three foot border around his room.
First, the whole area of his room is 20 x 24 = 480
Next, we have to make the measurements 3 feet smaller on each wall, so 17 x 21 = 357
Finally, to find the area of the border, we simply do 480 - 357 = 123
He needs to buy 123 square feet of carpeting
Hope this helps!

Answer:
Step-by-step explanation:
<u>Surface area comprises of:</u>
- A = Area of square base + 4(area of triangle faces)
- A = 2.5² + 4*1/2*2.5*5= 31.25 cm²
Correct option is C
Area of the triangle at the top=1/2basexheight
1/2x10x 2= 10
Area of rectangle =length xwidth
9x10=90
Total area =area of triangle +area of rectangle
90+10=100m^2
