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
