I think that the answer is C
Hey there!
We need to find the area of the hole. Let’s start off with the top rectangle. The sides are 11 and 3. Multiply the two numbers to get 33. Add the sqaure on the bottom. 3 x 2=6. Add the two shapes to get 39. The answer would be 39 ft 2.
I hope this helps!
(n+5)^2=48
sqrt both sides
n+4=+/-4√3
minus 4 both sides
n=-4+/-4√3
-4+4√3>0 so this cannot be the value of n
n=-4-4√3
the number is -4-4√3
