Question

2. Find the area of the polygon given in the figure below: 5 cm 10 cm 5 cm 6 cm 6 cm​

Answer 1

Answer:

Area of all triangles = Area of triangle AFM + Area of triangle EOD + Area of triangle ALB + Area of triangle NCD =

21×AM×FM+21×EO×OD+21×AL×LB+21×ND×NC

21×20×20+21×60×30+21×10×30+21×40×40

200+900+150+800=2050

Area of all trapezium = Area of FMOE+ Area of LNCB

21(FM+EO)×MO+1/2×(LB+NC)×LN

21×(20+60)×40+1/2×(30+40)×40

=3000

area of the polygon =Area of all triangles +  Area of all trapezium

A=2050+3000=5050cm2

Answer (D) 5050cm
