Answer:

The area of the irregular figure is
366\ cm^(2)

Explanation:

we know that

The area of the irregular figure is equal to the area of rectangle plus the area of triangle

The area of rectangle is equal to


A=14*21=294\ cm^(2)

The area of triangle is equal to


A=(1)/(2)(16)(21-12)=72\ cm^(2)

Sum the areas


294\ cm^(2)+72\ cm^(2)=366\ cm^(2)
