Question

find the area of the following figure whose dimensions are shown

Answer 1

first area = 50*80 = 4000cm sq
now the left above triangle area = 1/2*base*height
= 1/2*50*20 = 500cm sq
and above rectangle area = 20*50 = 1000cm sq
now area of figure = (4000+1000-500)cm sq
= 5000-4500 = 4500 cm sq
