Answer 1

Heya !!

$Side \: Of \: Square \: = \: (\sqrt{5} + \sqrt{3}) \: cm \: .... \\ \\</p><p>Area \: of \: square \: = (side)^2 = (\sqrt{5} + \sqrt{3})^2 \\ \\</p><p>= (\sqrt{5})^2 + 2(\sqrt{5})(\sqrt{3}) + (\sqrt{3})^2 \\ \\</p><p>= 5 + 2\sqrt{15} + 3 \\ \\</p><p>= (8 + 2\sqrt{15}) \: cm^2 \:.......$

Hope it helps !!

Q: find area of square whose side is (√5+√3).

=> Area of square = ( side)²

= (√5+√3)²

= (√5)² + (√3)² +2×√5×√3

= 5 + 3 + 2√15

= 8+2√15

= 15.74 approx.



Hence,
Area of square = 15.74
