Answer:
12.73m
Step-by-step explanation:
using Pythagoras theorem
a = x (i change x to a for easy reference due to multiplication)
18 x 18 = a x a + a x a
324 = 2a^2
a^2 = 324 / 2= 162
a = = 12.7279 = 12.73 (2 decimal place)

Answer: Option B.
Step-by-step explanation:
If a varies directly with b then when a increases b it also increases by a factor k.
Then we can write that
We know that when a = 28 then b = 7. So
Therefore the equation of proportionality is:
So when then:
