Question

Find the area of the irregular figure

Answer 1

Rectangle=21 times 14=294 cm^2
Triangle=Base Times Height 
Height=21-12=9cm
Area of triangle=16 times 9 =144

Area of both=294+144=438cm^2

Answer 2

Answer:

The area of the irregular figure is $366\ cm^{2}$

Step-by-step 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

$A=\frac{1}{2}(16)(21-12)=72\ cm^{2}$

Sum the areas

$294\ cm^{2}+72\ cm^{2}=366\ cm^{2}$
