First, put each grade in terms of x. Most grades are compared to Sophomores, so I made that x
Freshmen = x + 10
Sophomores = x
Juniors = x + 20
Seniors = (x + 10) + 7 = x + 17
Then, the total number of students = 363, so we’ll make an equation that adds them all up in terms of x to equal 363
(x + 10) + x + (x + 20) + (x + 17) = 363
Combine like terms:
4x + 47 = 363
Subtract 47 from both sides:
4x = 316
Divide both sides by 4:
x = 79
The question was how many seniors there are. Seniors were x + 17, so 79 + 17 = 96

Answer: Area: 99cm Perimeter: 40cm
Step-by-step explanation:
To find the area, you would multiply 9cm by 11cm because the formula for area is length times width. To find the perimeter, you add all the sides, which would mean you add 9 + 9 + 11 + 11, making the perimeter 40cm.
