can you clarify this question? it’s quite confusing, but i’d like to help you.
The lateral area is 192 cm².
The lateral area is the area of all of the lateral faces. Since the base of the pyramid is a quadrilateral, there are 4 lateral faces. The area of one lateral face is 48 cm²; this means the lateral area is 48(4) = 192 cm².
The work is shown in the attached images. Each equation is labeled for slope intercept and standard form
y=-1/5x +18/5
5y+x=18
Convert the percent to a decimal
.15
Then, multiply 700 by 0.15 = 105.
Next, add 60 to 105 to get 165.
Finally, do 700-165=535.
Answer: $535
