Answer 2

Answer:

Given : ABCDEFGH is a octagon in which all sides is equal to 5 cm HC= 10 cm AL is perpendicular to HC & AL = 2 cm

Find area of octagon

Proof : By observation we see ABHC is a trapezium

so area = 1/2×(5+10)×2

= 15 cm ^2

HCGD is a rectangle

so area = 10×5 = 50 cm^2

draw FI is perpendicular to GD

so FI = AL and FE = AB ( By construction)

FEGD is a trapezium

area = 1/2×(5+10)×2

= 15 cm^2

hence

Area of Octagon = area of rectangle + area of trapezium + area of trapezium

=( 50+15 + 15)

= 80 cm^2
