उत्तर
Here we found two geometrical figures,
One is a triangle and the other is a trapezium.
Now,
Area of the Triangle = `1/2 xx 12 xx 25`
= 150 sq. cm
Area of Trapezium = `1/2 xx ( 25 + 15 ) xx ( sqrt(26^2 - ( 25 - 15 )^2))`
= 20 × 24
= 480 sq. cm
Hence, the area of the whole figure = 150 + 480
= 630 sq. cm
