प्रश्न
Calculate the area of the figure given below: which is not drawn scale.
उत्तर
Here we found two geometrical figures, one is a triangle and the other is the trapezium.
Now,
Area of the Triangle = `1/2` x 12 x 25
= 150 sq.cm
Area of Trapezium = `1/2 xx ( 25 + 15 ) xx ( sqrt(26^2 - ( 25 - 15 )^2))`
= 20 x 24
= 480 sq.cm
hence area of the whole figure = 150 + 480 = 630 sq.cm
