\frac{a \times a}{2} = 25 \Rightarrow a^{2} = 50

\frac{b \times b}{2} = \frac{a b}{2} + 84 \Rightarrow \frac{a^{2} b^{2}}{2 a^{2}} = \frac{a b}{2} + 84

l e t X = \frac{a b}{2} = u n k n o w n a r e a

\frac{X^{2}}{25} = X + 84

X^{2} - 25 X - 25 \times 84 = 0

\Rightarrow X = \frac{25 + 95}{2} = \frac{120}{2} = 60 ✓
