Area of trapezium= 1/2*d*(a+b) sq. Units.
Where d= perpendicular distance between parellel sides which are a & b respectively, 25 &13 cm.
25–13=12, 12/2= 6 cm is base of RT. Angled ∆.
Non parallel sides=10cm, this is hypotenuese of this ∆.
Find ‘d ‘ to solve.
d=√{10^2–6^2}=8 cm.
Area of trapezium= 1/2*8*(25+13)=152 cm^2
