Answer:

16.97 ft

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Side B = 21 ft

Side c = 27 ft

As we know, formula for right triangle is as follows,

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]a^{2} = c^{2} - b^{2}[/tex]

So, by putting the value in the formula, we get,

[tex]a^{2} = 27^{2} - 21^{2}[/tex]

[tex]a^{2}[/tex] = 729 - 441

[tex]a^{2}[/tex] = 288

a = 16.97 ft

Hence, the length of the side  for the right triangle is 16.97ft.
