Question

plzz explain how the answer of under root came 3.7 cm.plzz it's urgent

Answer 1

$Given : \sqrt{(\frac{3.5}{2})^2 + (3.25)^2}$

$= > \sqrt{(\frac{12.25}{4}) + (3.25)^2}$

$= > \sqrt{3.0625 + 10.5625}$

$= > \sqrt{13.625}$

$= > \sqrt{(3.7)^2}$

= > 3.7cm.

Hope this helps!

Answer 2

√(1.75)^2 + (3.25)^2

= √ (1.75+3.25)^2 - 2(1.75)(3.25)

= √(5)^2 - 11.375

= √25 - 11.375

= √ 13.625

= 3.6912

= 3.7 cm ( aprox).......
