A) 6
B) 3
C) (c)\[\frac{3}{2}\]
D) \[\frac{3}{4}\]
Correct Answer: C
Solution :
\[\because \] \[a=3,\] \[b=4\] and \[c=5\,cm\] \[\therefore \] \[\Delta \,ABC\] is a right angled triangle. \[\therefore \] \[ar\,(\Delta ABC)=\frac{1}{2}\times AC\times BC\] \[=\frac{1}{2}\times 4\times 3=6\,c{{m}^{2}}\] we also know that \[ar\,(\Delta PQR)=\frac{1}{4}(\Delta ABC)\] \[=\frac{1}{4}\times 6=\frac{3}{2}\,c{{m}^{2}}\]You need to login to perform this action.
