For problem 1, it will be 25/100, which is equal to 25%
2) The relationship is that both, the bar model and the proportion, show that x is 1/4 of the actual amount. The bar graph is more a visual. However, in both cases, the x can be solved for to be 25%
3) The percent error for 23°C will be less since it is closer to 25°C, the actual amount. The percent error is greater for 5°C since it is farther for 25°C.

marin [14]

Answer:

24 m^2

Step-by-step explanation:

There are two areas to consider here:  first, the area of the wall, and second, the area of the window.  We answer this question by finding these two areas and subtracting the area of the window from the area of the wall.

Wall area:  (4 m)(7 m) = 28 m^2

Window area:  (2 m)(2 m) = 4 m^2

Net area of wall, to be covered in brick:

28 m^2 - 4 m^2 = 24 m^2
