If C lies between A and B and AB =10 cm, AC =3 cm, then BC ^2= - Vidyadip

MCQ

If $C$ lies between A and B and $AB =10 cm, AC =3 cm$, then $BC ^2=$

A
$13 cm^2$
✓
$49 cm^2$
C
$9 cm^2$
D
$7 cm^2$

✓

Answer

Correct option: B.

$49 cm^2$

Since, $A B=10 cm, C=3 cm$, therefore $B C=A B-A C=10-3=7 cm$. Hence, $B C^2=49 cm^2$.
