120 pupils

2/5ths boys = 48 boys (120/5 * 2)

3/4s of boys write in pencil = 48 * 3/4 = 36

Girls = (120-48)-72

1/3 in pen so 24.

2/3 in pencil so 48

Area of rectangle is 128cm²

So use algebra to solve (remember area of rectangle = LxW)

2x * x = 128 (where 2x = length and x = width. Use 2x given length is twice width)

3x=128

2x²=128

x²=64

x=8

So perimeter = (8*4 for the length + 8*2 for the width) = 48cm
