Correct Answer: 2

Solution : Given: $\frac{(612+388)^2+(612-388)^2}{(612 \times 612)+(388 \times 388)}$
$= \frac{(612)^2 + (388)^2 +2 \times 612 \times 388 + (612)^2 + (388)^2 -2 \times 612 \times 388}{(612)^2 + (388)^2 }$
$= \frac{2[(612)^2 + (388)^2 ]}{(612)^2 + (388)^2 }$
$= 2$
Hence, the correct answer is 2.

Correct Answer: 539.712 cm²

Solution :

Area of the square = $\frac{1}{2}$ × (diagonal)²
= $\frac{1}{2}×32^2$
= $512$ cm²
Area of the equilateral triangle = $\frac{\sqrt3}{4}$×(side)²
= $\frac{\sqrt3}{4}×8^2$
= $16\sqrt3$ cm²
Total area = $512$ + $16\sqrt3$
= 512 + 27.712
= 539.712 cm²
