The area of wall B is \( 9.6 \mathrm{~m}^{2} \) What is the total area of walls that Peter and Katy need to paint?

To find the total area that Peter and Katy need to paint, you'll need to know the areas of all the walls they're painting. If wall B is \( 9.6 \mathrm{~m}^{2} \), you'll need to calculate the areas of the other walls (if any) and add them together. For instance, if they are also painting walls A and C, and their areas are \( 10 \mathrm{~m}^{2} \) and \( 8 \mathrm{~m}^{2} \) respectively, just sum them up: Total Area = Wall A + Wall B + Wall C = \( 10 + 9.6 + 8 = 27.6 \mathrm{~m}^{2} \). Remember to double-check the lengths and heights of the walls for any adjustments! Have fun picking colors and slapping on that paint! It's like art but on a bigger canvas—can't wait to see how it turns out!
