Question

find the area of enclosed figure ​

Answer 1

Answer:

Area of the figure = 318 cm²

Step-by-step explanation:

We divide the figure into two parts, trapezium and rectangle

Total Area = area of trapezium + area of rectangle

Area of trapezium = 1/2 h(b1 +b2)

h=30-18=12 cm

b1=5 cm

b2=12 cm

Area =1/2 ×12(5+12)

=6×17

=102 cm²

Area of rectangle = lb= 18×12=216 cm²

Total area=216 + 102

=318 cm²
