Confusing to me, sorry i cant help. I am not good with graphs.
Number of students on the football team: 1 3/4x16= 12
There are fewer than 16 on the football team.
There are 12 students in the football team.
To find the surface area of this figure, we simply have to add up the individual areas of the shapes that make up the figure.
Surface area = 4(area of triangle) + area of square
Surface area = 4 ( 1/2 * base * height) + side^2
Surface area = 4( 1/2 * 6 * 7) + 6^2
Surface area = 4 (3 * 7) + 36
Surface area = 4(21) + 36
Surface area = 84 + 36
Surface area = 120 cm^2
Hope this helps!
