Step-by-step explanation:
Answer:
27
Step-by-step explanation:
![\sqrt{81}=9\\\sqrt{9}=3\\therefore 9x3=27](https://tex.z-dn.net/?f=%5Csqrt%7B81%7D%3D9%5C%5C%5Csqrt%7B9%7D%3D3%5C%5Ctherefore%209x3%3D27)
For
![S= \frac{a+b+c}{2}](https://tex.z-dn.net/?f=S%3D%20%5Cfrac%7Ba%2Bb%2Bc%7D%7B2%7D%20)
the area is
![area= \sqrt{S(S-a)(s-b)(s-c)}](https://tex.z-dn.net/?f=area%3D%20%5Csqrt%7BS%28S-a%29%28s-b%29%28s-c%29%7D%20)
find S
S=(10+11+12)/2=(33)/2=16.5
![area= \sqrt{16.5(16.5-10)(16.5-11)(16.5-12)}](https://tex.z-dn.net/?f=area%3D%20%5Csqrt%7B16.5%2816.5-10%29%2816.5-11%29%2816.5-12%29%7D%20)
![area= \sqrt{16.5(6.5)(5.5)(4.5)}](https://tex.z-dn.net/?f=area%3D%20%5Csqrt%7B16.5%286.5%29%285.5%29%284.5%29%7D%20)
![area= \sqrt{2654.444}](https://tex.z-dn.net/?f=area%3D%20%5Csqrt%7B2654.444%7D%20)
area=51.5212
rounded
52 square inches
