How would one go about this? Is there a certain equation I need to use?
you need to use the pythagoras therom formula: c^2=a^2+b^2
on the right angled traingle which has a base of 2 and a height of 5
s^2=2^2+5^2
s^2=4+25
s^2=29
s=√29
s=5.4cm (nearest tenth)
c²=a²+b²,
c²=2²+5²
c²=4+25
c²=29
c=√29
c=5.4(1dp)
s=5.4(1dp)
