A=924cm²

a(Side)=35cm

b(Base )=53cm

c (Side)=66cm

Using the formulas

 area =  \sqrt{s(s - a)(s - b)(s - c)}

s =  \frac{a + b + c}{2}

Solving forA

a =  \frac{1}{4} \sqrt{ - a { }^{4}  + 2(ab) { }^{2}  + 2(ac) {}^{2}  - b {}^{4}  + 2(bc ){}^{2}  - c {}^{4} }

 =  \frac{1}{4 }   \sqrt{ - 35 {}^{4}  + 2(35 \times 53) {}^{2}  + 2 (35 \times 66) {}^{2}  - 53 {}^{4} + 2(53 \times 66) {}^{2} - 66 {}^{4}   }

=924cm²
