Question

Find the area of the shaded triangle in the given figure.

Answer 1

This figure consist of $1$cm rectangle,$3$ unshaded and $1$ shaded triangle.

Area of rectangle$=8\times 6=48$sq.cm

Area of triangle $A=\frac{1}{2}\times 4\times 5=10$sq.cm

Area of triangle $B=\frac{1}{2}\times 6\times 3=9$sq.cm

Area of triangle $C=\frac{1}{2}\times 8\times 2=8$sq.cm

Area of shaded triangle$=$Area of rectangle$-$Area of unshaded triangle

$=48-(10+9+8)=48-27=21$sq.cm
