A)
area of a square card table=side x side

a²-2ab+b²=(a-b)(a-b)=(a-b)²

x²-50x+625=x²-2(25)x+(25)²=(x-25)²=(x-25)(x-25) (=side x side)

the side lengh of the talbe is: (x-25)

B)
Perimeter: 4(side)=4(x-25)=4x-100

The perimeter is : (4x-100)

so 331 minus 7 equals 324 so 324 divided into six buses is 54 so in each bus 54 students would go
