✪AnSwEr

${\tt{\red{\underline{\large{Given}}}}}$

• A polygon
• Made up of ∆ and rectangle

${\sf{\green{\underline{\large{To\:find}}}}}$

• Area of polygon

${\tt{\Large{\pink{\underline{Construction}}}}}$

• $\tt{AF\perp{BE}}$

☞Solution

Area of polygon = Area of ∆ + Area of Rectangle

AF=8-4=4

Area of polygon = Area of ∆ + Area of Rectangle

=>Area of polygon = 1/2 Breadth × Height+ Length × Breadth

=>Area of polygon= 1/2 ×15 ×4 + 15×4

=>Area of polygon= 30+ 60

=>Area of polygon=90cm

Hence the area of polygon is 90cm²
