So there are 240 students in the class

And if 30% are boys that means

\frac{30}{100}   \times 240 = 72

so out of the 72 boys if 25% take it

72  \times  \frac{25}{100}  = \frac{72}{4}  = 18

Ans: 18 boys take PE GCSE

w represents width

4w represents length

d represents diagonal

w2 + (4w)2 = d2

w2 + 16w2 = d2

17w2 = d2

±w√17 = d

 

The diagonal is the width times √17.
