Question

The length of the hypotenuse of a right angled $\Delta$ whose two legs measure $12cm$ and $0.35m$ is:

• A. $37cm$
• B. $3.72cm$
• C. $0.372cm$
• D. $37m$

Answer 1

The correct option is A $37cm$

$0.35m=0.35\times 100cm=35cm.$
We have,
$(hypotenuse{)}^2=(side{)}^2+(side{)}^2$
$=(12{)}^2+(35{)}^2$
$=144+1225$
$=1369$
Hypotenuse $=\sqrt{1369}=37cm.$
