75•15=1125 (this is the area of the bottom rectangle)
10•25=250 (area of the top rectangle)
Now add those together to get the area of the WHOLE shape 250+1125=1375
Answer:9/4
Step-by-step explanation:multiply 2.25 by 100 so you get 225/100 and reduce
The solution to the problem is as follows:
If you meant, Square root of 32:

Well we know that he can paint 350 square feet in 1.25 hours. To find how much he can paint in 1 hour, we would divide 350 by 1.25. 350 divided by 1.25 = 280, therefore his painting rate is 280 square feet per hour.
Rules to use
Rule 1: x^2 = x*x
Rule 2: (a+b)*(c+d) = a*(c+d)+b*(c+d)
Rule 3: a*(b+c) = a*b+a*c
Using those rules, we get the following
(6+u)^2 = (6+u)*(6+u) ... use rule 1
(6+u)^2 = 6*(6+u)+u*(6+u) ... use rule 2
(6+u)^2 = 6*6+6*u+u*6+u*u ... use rule 3
(6+u)^2 = 36+6u+6u+u^2 ... multiply
(6+u)^2 = u^2+12u+36 ... combine like terms and rearrange
Answer: u^2+12u+36
