Answer:
y=-1
Step-by-step explanation:
14-(.5*30) same as dividing 30 by 2
14-15=-1 combine
65:100 because there are 65 girls and then 65 girls + 35 boys = 100 total students
Width: x
Length: 2x
Perimeter=2x+2x+x+x=6x
32 cm more than width means x+32
6x=x+32
5x=32
x=6.4
Dimension is 6.4×12.8 (width×length)
