Answer:
16.97 ft
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,
![a^(2) + b^(2) = c^(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/np5o9ivdu7vwogdwt92j6b2xw98vc0ty49.png)
![a^(2) = c^(2) - b^(2)](https://img.qammunity.org/2022/formulas/mathematics/middle-school/4wuo2qqoeemecctbjbcqil2j2d08j0751w.png)
So, by putting the value in the formula, we get,
![a^(2) = 27^(2) - 21^(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/qlck5cpzq6th0ddqf6nfwxza3ha542hs7s.png)
= 729 - 441
= 288
a = 16.97 ft
Hence, the length of the side for the right triangle is 16.97ft.
