Answer:
D. 420
The area of a triangle is

half of(base× height)
10×16= 160
160÷2=80
That is the surface area of ONE triangle.
multiply 80 by 4 to get 320
then find the surface area of the square by doing length×width to get 100
Finally add them together
320+100=420
Given:
15 students
average grade: 80 for 14 students
average grade: 81 for 15 students
80 * 14 = 1120
81 * 15 = 1215
1215 - 1120 = 95
Payton's score on the test is 95.
