Answer 2

Find the area of the octagonal figure.

• To find the area, let us divide the figure into further smaller well known ones for better understanding.
• Area of the octagon = Area of HCDG + ABCH + FEDG
• Area of HCDG = 5 × 8 = 40cm²
• Area of ABCH =
• $\frac{1}{2} \times (sum \: of \: parallel \: sides) \times height$
• As the figure is a trapezium.
• $\frac{1}{2} \times 3 \times 8</em><em>+</em><em>5</em><em>$
• Area = 19.5cm²
• Area of FEDG = 19.5cm² [as the Quadrilateral has the same measurements as ABCH]
• Total area = 40 + 19.5 + 19.5 = 79cm²

Hope it helps!!

have a great day!!
